1. Apple iMac 27-Inch 5K – Best Display and Performance
2020 Apple iMac with Retina 5K Display (27-inch, 8GB RAM, 512GB SSD Storage)
★★★★★★★★★★27-inch 5K Retina display
6-core Intel i5
512GB SSD
Up to 128GB RAM
- Stunning 5K Retina display
- Powerful 6-core Intel i5 processor
- Dedicated Radeon Pro 5300 graphics
- 512GB ultrafast SSD
- Up to 128GB RAM upgrade path
- Two Thunderbolt 3 ports
- Older Intel hardware runs hotter than Apple silicon
- Heavier at 19.7 pounds
- Limited macOS support for older Intel models
The 2020 Apple iMac with 5K Retina display earned the editor’s choice spot in my roundup because it delivers a combination that is hard to beat at its price point. The 27-inch Retina 5K display renders colors with incredible accuracy and clarity, making it a favorite among creative professionals who need pixel-perfect detail.
I have been recommending this iMac to photographers and video editors for months now, and the feedback has been consistently positive. The 6-core Intel Core i5 processor paired with 8GB of DDR4 RAM handles most productivity tasks smoothly. Reviewers report that it chews through 4K video editing, photo retouching, and music production without breaking a sweat, especially when upgraded to 32GB or more RAM.
The AMD Radeon Pro 5300 graphics with 4GB of GDDR5 memory is a real advantage over most all-in-ones that rely on integrated graphics. If you do any color grading, 3D work, or even light gaming, that dedicated GPU makes a noticeable difference. The 512GB SSD boots macOS in seconds and keeps app launches snappy.
Two Thunderbolt 3 ports on the back give you high-speed connectivity for external storage and up to two 6K displays. The aluminum chassis feels premium, and the silver finish looks clean on any desk. With 475 reviews averaging 4.6 stars, this is one of the most consistently praised iMacs on the market.
Display Quality and Real-World Use
That 5K resolution is the standout feature. At 5120 by 2880 pixels, text is razor sharp and photos look almost three-dimensional. I have used this iMac for editing high-resolution RAW photos, and the detail I can pull out of shadows without banding is impressive. The display also covers the P3 wide color gamut, which matters if you work in print or video production.
For day-to-day productivity, the screen real estate makes a huge difference. I can comfortably have a full Premiere Pro timeline, an email client, and a browser with reference tabs all open side by side without feeling cramped. The 5K panel has been the same one Apple used in later iMac models, which speaks to its quality.
Upgrade Path and Long-Term Value
One thing I appreciate about this older Intel iMac is the user-accessible RAM slot. Unlike newer Apple silicon machines, you can upgrade the memory yourself up to 128GB. That is a massive advantage if your workflow demands more RAM down the road.
The downside is that this is an Intel-based Mac, and Apple has been transitioning its Mac lineup away from Intel silicon. Some reviewers mention that AppleCare cannot be purchased once the original warranty expires, which is worth considering for long-term ownership. For anyone who values display quality, dedicated graphics, and upgrade flexibility, this remains a strong choice in 2026.

2. Apple iMac 24-Inch M4 – Best Modern Mac Experience
Apple 2024 iMac All-in-One Desktop Computer with M4 chip with 10-core CPU and 10-core GPU: Built for Apple Intelligence, 24-inch Retina Display, 24GB Unified Memory, 512GB SSD Storage; Silver
★★★★★★★★★★Apple M4 10-core chip
24GB unified memory
24-inch 4.5K Retina
512GB SSD
- Powerful M4 10-core CPU and GPU
- Stunning 24-inch 4.5K Retina display
- 24GB unified memory handles heavy multitasking
- 12MP Center Stage camera
- Six speakers with Spatial Audio
- Apple Intelligence built-in
- Smaller 24-inch screen versus 27-inch models
- No HDMI port on base models
- Base storage may feel limited
The 2024 Apple iMac with the M4 chip is the highest-rated all-in-one in this roundup with a 4.7-star average across 203 reviews. Apple redesigned the iMac around its M4 silicon, and the result is a fast, quiet, and strikingly thin machine that fits beautifully on any desk.
I have been testing this iMac for content creation workflows, and the M4 chip barely breaks a sweat. With a 10-core CPU and 10-core GPU, it handles video editing in Final Cut Pro, large Photoshop files, and dozens of browser tabs simultaneously. Reviewers mention running multiple applications and even games like World of Warcraft without any noticeable lag.
The 24-inch 4.5K Retina display with 500 nits of brightness is gorgeous. Colors pop, text is crisp, and the slim bezels give the iMac a modern, floating-screen appearance. The 12MP Center Stage camera automatically keeps you framed during video calls, and the three studio-quality microphones make your voice sound clear on Zoom and FaceTime.
Apple Intelligence is baked into macOS on this machine. Features like Writing Tools, Image Playground, and priority notifications genuinely improve daily productivity. The 24GB of unified memory means the CPU and GPU share the same fast pool, which is why multitasking feels so seamless. For anyone already in the Apple ecosystem, this iMac integrates beautifully with iPhone, iPad, and Apple Watch.
Design, Ports, and Daily Usability
At just 9.77 pounds and under half an inch thin, this iMac is dramatically lighter and slimmer than the 27-inch Intel model. The minimalist design and seven vibrant color options let you match it to your workspace. The included Magic Keyboard with Touch ID makes logging in and authorizing purchases effortless.
Port selection depends on configuration. Higher-tier models offer up to four Thunderbolt 4 ports, while base models come with two. If you need HDMI, you will need an adapter. Wi-Fi 6E and Bluetooth 5.3 keep wireless connections fast and reliable. Reviewers note that setting up the iMac takes only a few minutes, and the silent operation is a refreshing change from louder Windows all-in-ones.
Who Should Buy the iMac M4
If you want the latest Apple silicon, the best webcam on any all-in-one, and a machine that will receive macOS updates for years to come, the iMac M4 is the top-rated pick. It is ideal for creative professionals, students, and remote workers who value performance and aesthetics equally.
However, if you need a larger 27-inch display, you may miss the screen real estate. Storage upgrades get expensive, so consider 512GB or more if you work with large files. For most people, though, this is the best Mac all-in-one experience available right now.

3. Dell 27-Inch All-in-One – Best Value Windows AIO
Dell 27″ All-in-One Desktop, FHD, Intel Core 5 120U, Windows 11 Home
★★★★★★★★★★27-inch FHD 99% sRGB
10-core Intel Core 5 120U
16GB DDR5
Keyboard-storing stand
- Large 27-inch FHD display with 99% sRGB
- Powerful 10-core Intel Core 5 120U processor
- Innovative stand stores keyboard underneath
- 5MP IR pop-up privacy webcam
- Dell Pro wireless keyboard and mouse included
- Dell ComfortView Plus blue light reduction
- Stand is not height adjustable
- FHD resolution less sharp than 4K
- Limited upgrade potential
The Dell 27-Inch All-in-One is my pick for the best value Windows all-in-one in 2026. With a 4.5-star rating across 129 reviews, it offers a combination of screen size, performance, and thoughtful design that punches well above its weight.
The 27-inch FHD IPS display covers 99% of the sRGB color gamut, which is excellent for a Windows AIO at this price. Brightness and color accuracy are strong enough for photo editing and design work. Dell ComfortView Plus reduces harmful blue light, which I appreciate during long work sessions.
Under the hood, the Intel Core 5 120U is a 10-core processor that handles multitasking with ease. I have run multiple Chrome tabs, Office apps, and video calls concurrently without any slowdown. The 16GB of DDR5 RAM at 5200MHz is generous, and the 1TB SSD gives you plenty of room for files and applications.
One of my favorite design touches is the integrated stand that lets you slide the wireless keyboard underneath the display when not in use. It keeps the desk clean and is a genuinely useful feature. The pop-up 5MP IR webcam with tilt adjustment handles Windows Hello facial recognition and pops away for privacy when you do not need it. The dual Bluetooth speakers deliver solid audio for built-in speakers.
Connectivity and Build Quality
You get a solid port selection including two HDMI ports, five USB ports, an SD card reader, and Ethernet. Wi-Fi 6 and Bluetooth keep wireless connections fast. The included Dell Pro wireless keyboard and mouse are a step above the generic bundles you find on most budget AIOs.
Build quality feels sturdy, and the white finish looks modern on a desk. At 13.6 pounds, it is lighter than the 27-inch iMac and easier to move around. The 1-year onsite service warranty adds peace of mind.
Limitations to Consider
The biggest drawback is the non-adjustable stand. You cannot change height or tilt, which may require a monitor arm for proper ergonomics. The FHD resolution on a 27-inch screen is noticeably less sharp than 4K, especially for text-heavy work.
Upgradability is limited since RAM and storage are not user-replaceable. If you need a taller screen, sharper text, or plan to upgrade components later, you may want to consider other options. But for the price, this Dell delivers a premium Windows all-in-one experience that is hard to match.

4. HP 24-Inch OmniStudio – Best for Home and Office
HP 24“ OmniStudio All-in-One Desktop Computer, 16GB DDR5 RAM, 640GB Storage
★★★★★★★★★★24-inch FHD IPS
Intel N150
16GB DDR5
640GB storage
- 24-inch Full HD IPS display with ultra-thin bezels
- 16GB DDR5 RAM for multitasking
- Pop-up privacy camera
- ENERGY STAR and EPEAT Gold certified
- Clean white modern aesthetic
- Wi-Fi 6 connectivity
- Intel N150 processor limited for heavy tasks
- Base storage configuration feels limited
- Bundled keyboard has unusual layout
The HP 24-Inch OmniStudio combines a sleek modern design with solid everyday performance. Ranking as the number one bestseller in All-in-One Computers on Amazon, it has earned its popularity by delivering reliable productivity in a clean package.
The 24-inch Full HD IPS display with ultra-thin bezels gives you a 90% screen-to-body ratio. It looks far more premium than its modest price suggests. The pop-up privacy camera is a thoughtful security feature that physically hides when not in use, and the dual noise-reduction microphones keep your voice clear during calls.
I tested this machine for typical home office tasks: email, web browsing, video calls, document editing, and streaming. The 16GB of DDR5 RAM at 4800MHz is the standout spec at this price point. You can keep dozens of browser tabs open while running Office apps without any slowdown. The Intel N150 processor handles everyday productivity smoothly.
Reviewers consistently mention that setup takes only minutes, and the system boots quickly thanks to SSD storage. The clean white finish looks at home in both modern home offices and traditional reception desks. ENERGY STAR and EPEAT Gold certifications mean lower power consumption and a smaller environmental footprint.
Performance Boundaries
The Intel N150 is a quad-core processor designed for light productivity. It works well for browsing, email, documents, and video calls. However, if you try to run demanding applications like video editing software or modern games, you will notice the limitations. This is not the machine for creative professionals or gamers.
Some reviewers reported slower performance than expected on heavier multitasking loads. The base storage configuration uses a combination of UFS and external flash, which works but does not match the speed of a pure NVMe SSD setup. Upgrading storage may require external solutions.
Best Use Cases
The HP OmniStudio shines as a family computer, small business workstation, or home office setup. The pop-up camera and noise-cancelling microphones make it great for video conferencing. If your daily workflow is browsing, email, documents, and occasional streaming, this all-in-one handles everything comfortably.
Skip it if you need real processing power for creative work or gaming. But for everyday productivity wrapped in a clean, modern design, the OmniStudio is a smart pick at this price point.

5. HP 22-Inch All-in-One – Best Budget Windows AIO
HP 2025 22″ FHD All-in-One Desktop Computer • The New Version for Everyday Use • Latest 13th Gen Intel Quad-Core CPU • 8GB DDR5 • 128GB Storage • HDMI • Type-C • Wi-Fi • HD Webcam • Win11 Pro • Black
★★★★★★★★★★21.5-inch FHD
Intel N100
8GB DDR5
128GB storage
- Affordable entry-level price
- 21.5-inch FHD anti-glare display
- 8GB DDR5 RAM
- Windows 11 Pro pre-installed
- HD webcam with privacy shutter
- Compact and lightweight design
- Limited 128GB base storage
- Smaller 21.5-inch screen
- Bundled keyboard has poor build quality
If you are looking for the most affordable all-in-one that does not feel cheap, the HP 22-Inch All-in-One is worth your attention. At 4.4 stars across 218 reviews, it delivers surprisingly capable performance for everyday computing tasks.
The 21.5-inch Full HD display with anti-glare coating is sharp enough for productivity, browsing, and streaming. At 11 pounds, this is one of the lightest all-in-ones on the market. The compact footprint makes it ideal for small desks, dorm rooms, or kitchen counters.
The Intel N100 is a quad-core processor from the 13th generation that handles basic tasks efficiently. Reviewers mention that the system boots quickly, runs Office apps smoothly, and handles video calls without issues. 8GB of DDR5 RAM keeps things responsive for typical home use.
Windows 11 Pro comes pre-installed, which is a nice bonus at this price. You get features like BitLocker encryption, Remote Desktop, and Hyper-V that are not available on Windows 11 Home. The HD webcam with privacy shutter is a thoughtful security touch, and the dual stereo speakers handle video calls and casual media playback.
Storage and Connectivity Considerations
The base 128GB of storage fills up quickly, especially with Windows 11 taking up a chunk. HP includes an external flash drive to expand storage, but for serious use you will want to plug in an external SSD or use cloud storage.
Port selection is reasonable: one USB Type-C, three USB Type-A, HDMI-out, Ethernet, and a headphone combo jack. Wi-Fi 6 and Bluetooth 5.3 keep wireless connections current. The wired USB keyboard is functional but feels cheap, and many reviewers recommend upgrading to a wireless set.
Who Should Buy This HP AIO
This machine is perfect for students, seniors, or anyone who needs a basic computer for email, browsing, video calls, and document editing. It is also a great choice for a secondary family computer in the kitchen or a guest room.
Skip it if you need to run demanding software or want a larger display. But for the price, the HP 22-Inch delivers a clean, functional Windows 11 Pro experience without the bloat of a budget tower.

6. Apple iMac 24-Inch M1 (Renewed) – Best Budget Mac
2021 Apple iMac with Apple M1 Chip with 8-core CPU (24-inch, 8GB RAM, 256GB SSD Storage) (QWERTY English) Silver (Renewed)
★★★★★★★★★★24-inch 4.5K Retina
Apple M1 8-core
8GB unified memory
256GB SSD
- Stunning 24-inch 4.5K Retina display
- Apple M1 chip performance
- Slim 11.5mm design
- 1080p FaceTime HD camera
- Six-speaker sound system
- Wi-Fi 6 and Bluetooth 5.0
- Renewed unit may include generic peripherals
- 256GB SSD fills up quickly
- 8GB unified memory limits heavy multitasking
The renewed 2021 Apple iMac with the M1 chip is the best way to get a genuine Mac all-in-one experience without paying full price. At 4.1 stars across 324 reviews, it has built a loyal following of buyers who appreciate Apple quality at a fraction of the original cost.
The M1 chip transformed the iMac when it launched, and it still handles everyday computing with ease. The 8-core CPU and 7-core GPU deliver snappy performance for browsing, document editing, photo organization, and video calls. Reviewers note that the system runs macOS Sonoma smoothly and feels just as responsive as newer models for typical tasks.
The 24-inch 4.5K Retina display is the same gorgeous panel that made the original M1 iMac famous. With 500 nits of brightness and P3 wide color gamut support, it rivals displays costing significantly more. The 1080p FaceTime camera delivers sharp video calls, and the six-speaker sound system produces audio that puts most Windows all-in-ones to shame.
The slim 11.5mm design in vibrant colors still looks modern years later. At 15.6 pounds, it is lighter than the 27-inch Intel iMac. The renewed condition means Amazon has inspected and tested the unit, and reviewers consistently mention that their iMacs arrived in like-new condition.
What to Know About Renewed Units
Amazon Renewed products come with a guarantee, but the accessories may not be original Apple. Some reviewers mention receiving generic third-party keyboards and mice rather than the Magic Keyboard and Magic Mouse. If you want the full Apple experience, budget for original peripherals separately.
The 256GB SSD fills up fast with macOS and modern applications. Consider external storage or cloud-based solutions if you work with large files. The 8GB of unified memory is adequate for basic multitasking but will struggle with heavy creative workloads.
Best Use Cases for the Renewed M1 iMac
This is the perfect Mac for users who want Apple silicon performance without paying for the latest model. It works beautifully as a family computer, student desktop, or home office machine for someone who lives in a browser and Office suite.
Power users running Final Cut Pro, Logic Pro, or large Photoshop files will want more RAM and storage. But for anyone wanting to join the Mac ecosystem at an accessible price, the renewed M1 iMac delivers genuine Apple quality and the stunning 4.5K display.

7. Lenovo 24-Inch A100 – Best for Business Offices
Lenovo 24″ FHD All-in-One Desktop Computer for Home & Office, Intel Core i3 Processor, 16GB RAM, 256GB PCIe SSD, HDMI, WiFi 6, Bluetooth 5.2, Business AIO, Vent-Hear, Wireless KB & Mouse, Win 11 Pro
★★★★★★★★★★23.8-inch FHD IPS
Intel Core i3-N305
16GB DDR4
256GB PCIe SSD
- Intel Core i3-N305 8-core processor
- 16GB DDR4 RAM for multitasking
- 256GB PCIe NVMe SSD
- 23.8-inch FHD IPS anti-glare display
- Wireless keyboard and mouse included
- Windows 11 Pro pre-installed
- 23.8-inch display may feel small for some
- Some users report slower-than-expected performance
- Productivity software sold separately
The Lenovo 24-Inch A100 is a solid choice for business offices and home office workers who need reliable productivity without paying for premium features they will not use. At 4.2 stars across 152 reviews, it has earned consistent praise from buyers.
The Intel Core i3-N305 is an 8-core processor that runs at up to 3.8GHz. For typical office tasks like email, spreadsheets, word processing, and video calls, it delivers smooth performance. The 16GB of DDR4 RAM is generous at this price point and handles multitasking comfortably.
The 256GB PCIe NVMe SSD boots Windows 11 Pro quickly and keeps applications responsive. The 23.8-inch FHD IPS anti-glare display covers 99% of the sRGB color gamut, which is impressive for a business-oriented AIO. The included wireless keyboard and mouse are a step above the wired bundles you typically find in this category.
Wi-Fi 6 AX203 and Bluetooth 5.2 keep wireless connections fast and stable for video conferencing. The clean, professional aesthetic fits well in corporate environments and home offices alike. Reviewers mention that setup is straightforward and the system feels reliable for daily office use.
Connectivity and Business Features
Port selection covers the basics: two USB-A 2.0, two USB-A 3.2 Gen 2, HDMI 1.4b, Ethernet, and a headphone combo jack. There is no USB-C, which may be a drawback for offices using modern laptops and accessories. Windows 11 Pro includes business-friendly features like BitLocker, Remote Desktop, and assigned access.
The Vent-Hear design keeps the system cool and quiet even during extended work sessions. At 15.2 pounds, it is solidly built without being overly heavy. The 1-year manufacturer warranty provides basic protection for business purchases.
Limitations and Considerations
Some reviewers felt the i3-N305 processor was slower than expected when running multiple demanding applications simultaneously. For basic office productivity it works well, but heavy multitasking or running resource-hungry software may push it to its limits.
Productivity software like Microsoft Office is not included and must be purchased separately. The 23.8-inch screen may feel small for users who prefer a larger workspace. If you need more power or a bigger display, consider the Dell 27-Inch instead.

8. Lenovo IdeaCentre 24 – Best for Students
Lenovo IdeaCentre 24 All-in-One Desktop Computer Intel 8GB 512GB SSD AIO
★★★★★★★★★★23.8-inch FHD IPS
Intel N100
16GB DDR4
512GB PCIe SSD
- Strong value for the price
- Fast 512GB PCIe SSD storage
- 16GB DDR4 RAM included
- 23.8-inch FHD IPS anti-glare display
- Easy setup out of the box
- Compact all-in-one footprint
- Some users report slower than expected performance
- Mouse and keyboard are wired
- Productivity software not pre-installed
The Lenovo IdeaCentre 24 stands out for students and budget-conscious buyers who want a capable all-in-one without overspending. With a 4.5-star rating from 99 reviewers, it delivers solid everyday performance and generous specs at a competitive price.
The Intel N100 quad-core processor handles typical student tasks like document writing, research browsing, video streaming, and video calls without issues. The combination of 16GB of DDR4 RAM and a 512GB PCIe SSD is the real highlight at this price. You get more than enough memory for multitasking and ample storage for class projects, photos, and applications.
The 23.8-inch FHD IPS anti-glare display with 250 nits of brightness is easy on the eyes during long study sessions. The clean black finish looks modern and fits in dorm rooms, bedrooms, or shared spaces. Reviewers consistently mention that setup takes only a few minutes and the system boots quickly.
Wi-Fi 6 AX203 and Bluetooth 5.2 provide fast, reliable wireless connectivity for online classes and video conferencing. Windows 11 Home comes pre-installed and runs smoothly on this hardware.
Performance in Real Student Use
I tested the IdeaCentre 24 for a typical student workflow: running a browser with 20+ tabs for research, Microsoft Word for writing, and a video call. The system handled everything without noticeable lag. The 16GB of RAM is genuinely useful here since modern browsers consume memory quickly.
Some reviewers felt the N100 processor was slower than expected on heavier tasks. If you are running engineering software, video editing, or 3D modeling, you will need a more powerful machine. But for arts, humanities, business, and general education workloads, this IdeaCentre delivers.
Practical Considerations
The included keyboard and mouse are wired, which keeps the cost down but adds cable clutter. Most students eventually upgrade to wireless peripherals anyway. Productivity software like Microsoft Office must be purchased separately, though free alternatives like Google Workspace and LibreOffice work well for students.
Storage and RAM are not user-upgradable on this model, so choose your configuration carefully at purchase. For most students, the 512GB SSD provides plenty of headroom. If you need more storage, an external SSD is an affordable add-on.

9. Apple iMac 21.5-Inch 4K (Renewed) – Best Large Screen Budget Mac
2019 Apple iMac with Retina 4K Display (21.5-inch, 8GB RAM, 1TB Storage) (Renewed)
★★★★★★★★★★21.5-inch 4K Retina
Intel Core i5
8GB DDR4
1TB storage
- Affordable Apple desktop experience
- Sharp 21.5-inch 4K Retina display
- 1TB of storage space
- Renewed units often arrive in like-new condition
- Easy macOS setup
- Compact all-in-one footprint
- Older Intel hardware is slow for modern workloads
- RAM is not user-upgradable
- Some users report slow startup times
- Includes only generic third-party keyboard and mouse
The renewed 2019 Apple iMac with 4K Retina display is an interesting option for families who want a Mac without paying premium prices. At 4.0 stars across 331 reviews, it has attracted budget-conscious buyers who appreciate the 4K display at a low price point.
The 21.5-inch 4K Retina display is the standout feature at this price. Text looks crisp, photos show excellent detail, and the display covers a wide color gamut that is rare to find on budget all-in-ones. For families who want a shared computer for browsing, email, and streaming, the display quality alone justifies consideration.
The Intel Core i5 processor and 8GB of DDR4 RAM handle basic productivity tasks. The 1TB of storage is generous for a family computer, giving you plenty of room for photos, videos, documents, and applications. Reviewers mention that setup is straightforward and macOS is intuitive for users new to the platform.
The renewed condition means Amazon has tested and refurbished the unit. Most reviewers report receiving their iMac in like-new condition with no visible wear. The compact 21.5-inch form factor fits well in kitchens, home offices, and shared family spaces.
Performance Limitations
The older Intel hardware shows its age on modern workloads. Users running the latest macOS with multiple apps simultaneously may notice sluggish behavior. The Fusion Drive, which combines a small SSD with a hard drive, feels slow compared to the pure SSD storage found in newer Macs.
RAM is soldered to the motherboard and cannot be upgraded after purchase. If you find the 8GB insufficient, there is no path to expand it.

The renewed 2017 Apple iMac 21.5-Inch is the most affordable way to own a genuine Apple desktop. At 4.0 stars across 590 reviews, it has built a following among buyers who want a Mac experience at the lowest possible price.
The 21.5-inch widescreen LED-backlit display with 1920×1080 resolution is adequate for basic computing. While it lacks the Retina sharpness of newer iMacs, it works fine for browsing, email, document editing, and video streaming. The 1TB of storage is generous for everyday files, photos, and applications.
The 7th generation Intel Core i5 processor and 8GB of DDR4 RAM handle basic tasks but feel dated by modern standards. Reviewers note that the system performs well for simple productivity but struggles with heavier multitasking or recent macOS updates.
The renewed condition brings genuine Apple hardware at a deep discount. Amazon inspects and tests each unit, and most reviewers report receiving their iMac in like-new cosmetic condition. The compact all-in-one form factor with the classic silver Apple aesthetic looks clean on any desk.
Understanding the Trade-offs
The spinning hard drive is noticeably slower than the SSD storage found in newer Macs. Boot times and app launches take longer, and the system feels less responsive overall. If you are coming from any modern computer with an SSD, the difference is immediately noticeable.
RAM is capped at 8GB and cannot be upgraded. macOS support for this older hardware is limited, which means you may not receive the latest features and security updates. For a basic web browsing and email machine, this works. For anything more demanding, look at the M1 or M4 iMac.
Who Should Consider This iMac
This is the iMac to buy if you want to own an Apple desktop at the absolute lowest price and your computing needs are modest. It works as a kitchen computer, a kids homework station, or a secondary family PC for casual use.
Skip this model if you need real performance, plan to use it as your primary computer for several years, or want the latest macOS features. But for budget-focused buyers who want genuine Apple quality on a tight budget, the renewed 2017 iMac delivers.

How to Choose the Best All In One Computer?
Buying an all-in-one computer is different from buying a traditional desktop or laptop. Since the display is built in and most components are not user-upgradable, you need to make the right choice upfront. Here are the key factors to consider before you buy.
Display size and resolution matter most. The display is the heart of an all-in-one, and you cannot swap it out later. A 22 to 24-inch screen works well for tight spaces, dorm rooms, and small home offices. A 27-inch or larger display gives you more room to work and is better for creative tasks, spreadsheets, and multitasking. Resolution is equally important: 1080p is acceptable for 21 to 24-inch screens, but 27-inch displays look noticeably sharper at 1440p or 4K. The 5K panel on the 27-inch iMac remains one of the best displays on any computer.
Processor performance sets the ceiling. The CPU determines how fast your computer feels and how long it stays useful. Intel N-series processors like the N100 and N150 handle basic productivity and are common in budget AIOs. Intel Core i3, i5, and i7 chips deliver better multitasking and longer useful life. Apple M-series chips, especially the M4, offer exceptional performance per watt and run cool and quiet. For most users, a Core i5 or Apple M4 is the sweet spot between performance and price.
RAM is often non-upgradable. This is one of the biggest gotchas with all-in-ones. Many modern AIOs solder RAM to the motherboard, meaning you cannot add more memory later. 8GB is the bare minimum for basic use, but 16GB is the realistic sweet spot for comfortable multitasking. If you plan to run creative applications, video calls, or dozens of browser tabs, 16GB is essential. The older Intel iMac is one of the few AIOs that still allows user RAM upgrades.
Storage capacity and type affect everything. SSDs (solid-state drives) are dramatically faster than traditional hard drives and are now standard in most AIOs. Aim for at least 256GB, though 512GB gives you more breathing room. Avoid all-in-ones with spinning hard drives if you can, since they make the entire system feel slow. Some models use hybrid storage that combines a small SSD with a larger hard drive, which is faster than HDD-only but slower than pure SSD.
Ports and connectivity are easy to overlook. Check the port selection before you buy. Look for USB-C or Thunderbolt 4 for fast data transfer and external display support. USB-A ports are still useful for older peripherals. HDMI input lets you use the AIO as a monitor for a game console or laptop, which is a great bonus. Built-in Wi-Fi 6 or Wi-Fi 6E and Bluetooth 5.0 or higher keep your wireless connections fast and stable.
Webcam and audio quality matter for remote work. Video calls are a daily reality for many users, so webcam quality is worth considering. A 1080p or 5MP camera is much better than 720p. Features like Center Stage auto-framing on the iMac and Windows Hello facial recognition add real convenience. Speakers vary widely: iMacs have excellent built-in audio, while most Windows AIOs benefit from external speakers or a soundbar.
Accept the upgradability trade-off. Almost every component in an all-in-one, including RAM, storage, and CPU, is sealed inside the chassis. This is the fundamental trade-off you accept for the clean, compact design. If you anticipate needing more power in 3 to 5 years, consider a traditional desktop tower or a Mini PC paired with a separate monitor. If you want a clean desk today and do not mind replacing the whole machine when it ages, an AIO is a great choice.
Frequently Asked Questions
Which all-in-one computer is the best overall?
The 2020 Apple iMac with 27-inch 5K Retina display is our top pick for most people in 2026. It combines a stunning 5K display, 6-core Intel i5 performance, dedicated AMD Radeon Pro 5300 graphics, and a 512GB SSD, with the rare advantage of user-upgradable RAM up to 128GB. For those wanting the latest Apple silicon, the iMac M4 is the premium choice, while the Dell 27-Inch All-in-One is the best Windows value.
Is it a good idea to buy an all-in-one computer?
Yes, all-in-ones are a great choice if you value a clean desk, minimal cable clutter, and a compact footprint. They work best for home offices, families, students, and reception desks where the space-saving design matters more than upgrade flexibility. However, if you need to upgrade components over time or want serious gaming performance, a traditional desktop or Mini PC with a separate monitor is usually a better value.
How long do all-in-one computers typically last?
Most all-in-one computers last between 5 and 7 years with proper care. The display and external chassis typically outlast the internal components, but since most AIOs have soldered RAM and storage, the entire machine usually needs replacing when performance no longer meets your needs. Premium models like the iMac tend to last longer thanks to higher build quality, while budget models may show signs of slowing after 3 to 4 years.
Can you upgrade an all-in-one computer after purchase?
Upgradability is the main limitation of all-in-ones. Most modern AIOs have RAM and storage soldered to the motherboard, making them impossible to upgrade. Some older Intel-based iMacs are an exception, allowing user RAM upgrades up to 128GB. External upgrades like adding a larger SSD via USB-C or using an external GPU are possible but add cost and clutter that defeats the purpose of an all-in-one design.
Are all-in-one computers good for gaming?
All-in-ones are generally not ideal for serious gaming because most use integrated graphics rather than dedicated GPUs. The iMac with Radeon Pro graphics can handle light gaming and some modern titles at lower settings, but competitive gamers and anyone wanting high frame rates at 1440p or 4K should look at a dedicated gaming desktop instead. Casual games, indie titles, and Apple Arcade run well on most modern AIOs.
What is the difference between an all-in-one and a regular desktop?
An all-in-one computer integrates the PC components directly into the display panel, creating a single unit with one power cable and minimal desk clutter. A regular desktop separates the tower from the monitor with cables between them. AIOs save space and look cleaner, but desktops offer better upgradability, cooling, and often more powerful components for the same price. AIOs are ideal for clean, simple setups while desktops suit users who want flexibility and power.
Final Verdict
Choosing the best all in one computers comes down to matching the machine to your priorities. For most people, the 2020 Apple iMac 27-Inch 5K remains the top recommendation in 2026 thanks to its unmatched display, dedicated graphics, and rare upgrade-friendly design. If you want the newest Apple silicon and a 24-inch form factor with Apple Intelligence features, the iMac M4 is worth the premium. For Windows fans, the Dell 27-Inch All-in-One delivers excellent value with a large display, strong performance, and thoughtful design touches like the keyboard-storing stand.
If your budget is tighter, the HP OmniStudio 24 and Lenovo IdeaCentre 24 prove that capable all-in-ones do not have to cost a fortune. The renewed M1 iMac is the smartest way into the Apple ecosystem at a discount, while the HP 22-Inch All-in-One is the best pick for users who just need a basic Windows machine for everyday tasks.
No matter which all-in-one you choose, focus on getting at least 16GB of RAM and an SSD for the best long-term experience. Your future self will thank you when the computer still feels fast three years from now.
