The best all-in-one desktops put a whole computer behind the screen — no tower, no cable nest, no wasted desk space. We tested and ranked the top AIOs of 2026 across macOS and Windows, from a $845 everyday workhorse to a 24-core business powerhouse.
- Best overall: Apple iMac M4 — the fastest, best-looking AIO you can buy if you’re on macOS.
- Best Windows: Lenovo Yoga AIO 27 — a genuine iMac alternative with a 120Hz QHD screen.
- Best value: Dell 24 All-in-One — a dependable home-office machine under $850.
- Best for creators: HP OmniStudio X 27 — big, bright Copilot+ touchscreen with 2TB storage.
- Best for business: Lenovo ThinkCentre M90a Gen 6 — 24-core Ultra 9, Thunderbolt 4, configurable.
An all-in-one desktop is the simplest full-size computer you can own. Everything — processor, memory, storage, speakers, webcam — lives inside the display, so setup is a single power cable and you’re working. That clean-desk appeal is why AIOs remain the default pick for home offices, reception desks, kitchens, dorms, and any space where a tower would just be clutter. If you’re still deciding between an all-in-one and a traditional tower, read our companion guide, Desktop vs. All-in-One, first — it covers the trade-offs in depth.
The catch is that all-in-ones ask you to buy right the first time. Most seal their components in, so the RAM and storage you choose at checkout are usually the RAM and storage you keep for the life of the machine. That makes picking the correct model more important than with a tower you can upgrade later — and it’s exactly what this guide is built to get right. Every pick below is a currently available, in-stock, Amazon-shipped listing with live pricing pulled straight from the product page. No dead links, no phantom configurations.

The best all-in-one desktops of 2026 — full reviews
1. Apple iMac M4 (24″) — Best Overall All-in-One
The iMac M4 is the machine every other all-in-one is measured against, and it earns that status. Apple’s M4 chip pairs a 10-core CPU with a 10-core GPU and glides through everything a mainstream desktop is asked to do — dozens of browser tabs, 4K video edits, big spreadsheets — while running cool and close to silent. It’s wrapped in the thinnest, most striking chassis in the category, available in seven colors, behind a 24-inch 4.5K Retina display that is still the best-looking screen you can get on an AIO. The six-speaker system with Spatial Audio and the 12MP Center Stage webcam round out a package that simply feels a tier above the Windows field in fit and finish.
The compromises are the familiar Apple ones. You get Thunderbolt 4 ports and nothing else — no USB-A, no HDMI — so older peripherals need a hub. The stand offers no height adjustment, the base model starts at 256GB (spend up to the 512GB configuration reviewed here), and unlike some Windows rivals the iMac can’t double as an external monitor for a laptop or console.
- Class-leading M4 performance, cool and silent
- Gorgeous, accurate 4.5K Retina display
- Premium included keyboard and mouse
- Best-in-class speakers and webcam
- Thunderbolt-only ports, no USB-A/HDMI
- No stand height adjustment
- Base storage starts at 256GB
- Can’t be used as an external display

The Yoga AIO 27 is the Windows machine that goes toe-to-toe with the iMac, and for shoppers who don’t want macOS it’s the one to buy. Its 27-inch QHD display runs at a smooth 120Hz, its Intel Ultra 7 255H actually edges the iMac M4 in some multi-core workloads, and Lenovo packs in genuinely useful extras: a Qi wireless charger built into the stand, a display that rotates 90 degrees for vertical content, and — the real trump card — HDMI-in, so you can use the screen as an external monitor for a laptop or console. It ships with 2TB of total storage (a 1TB SSD plus a 1TB docking drive), Wi-Fi 7, and Windows 11 Pro.
Where it slips behind the iMac is polish. The webcam is grainy by comparison, the panel is dimmer than the brightest rivals, the 16GB of LPDDR5X is soldered and can’t be expanded, and the included mouse feels cheap. None of that undoes the value — you’re getting a bigger, faster-refreshing, more flexible screen for several hundred dollars less than a comparably specced iMac.
- Fast Ultra 7; beats iMac in some multi-core tasks
- 27″ QHD 120Hz, rotates 90°
- HDMI-in doubles it as a monitor
- Built-in Qi charger, Wi-Fi 7, 2TB
- Grainy webcam
- Dimmer than key rivals
- 16GB soldered, not upgradable
- Flimsy included mouse

- Picture perfect: Look your best, even in challenging lighting conditions, thanks to HDR technology on the 5MP+IR camera….
Not everyone needs a $2,000 desktop, and the Dell 24 is the pick that proves it. For just under $900 it delivers everything a home office actually runs on: a crisp 23.8-inch Full HD touchscreen, an efficient Intel Core 5 120U, 16GB of DDR5, a fast 512GB SSD, and wireless keyboard and mouse in the box. Dell’s hardware-level ComfortView Plus reduces blue light without washing out color, and the 5MP HDR webcam with a physical privacy shutter is a genuinely nice touch at this price. With 200-plus units bought in the past month and a solid 4.4-star average across 135 ratings, it’s a proven, low-risk buy.
You are making sensible trade-offs for the price. The 120U is efficient rather than fast, so heavy creative work isn’t its lane; the 1080p panel isn’t as sharp as the QHD and 4K machines above it; and upgrade options after purchase are limited. For browsing, email, video calls, streaming, and everyday productivity, none of that matters.
- Genuinely affordable, proven track record
- FHD touchscreen with USB-C
- Privacy-shutter webcam + ComfortView Plus
- Wireless peripherals included
- Efficient, not powerful, CPU
- 1080p less sharp than QHD/4K rivals
- Limited post-purchase upgrades
- Merely adequate audio
Everything up to here covers the everyday-to-premium mainstream. Above roughly $1,400, you’re paying for one of three things: a bigger, sharper touchscreen (HP), the fastest processor and full expandability (ThinkCentre), or business-grade privacy and value (OptiPlex). Match the jump to the work you actually do — not the spec sheet.

The OmniStudio X 27 is HP’s big, modern, AI-forward all-in-one, and it’s the one to look at if you want a large touchscreen for media and light creative work. It runs Intel’s Core Ultra 7 256V with Arc 140V graphics — a Copilot+ class chip with a dedicated NPU for on-device AI features — backed by a generous 2TB SSD, the most storage in this lineup. The 27-inch touchscreen and adjustable stand make it a comfortable hub for photo culling, document review, and everyday content work, and it’s a strong choice for a family that wants one powerful shared machine.
One honest note: this specific 27-inch cs1010 model is a Full HD touchscreen, not the 4K panel some larger OmniStudio configurations carry — so if pixel-perfect 4K editing is the goal, size up within the OmniStudio line. As with most AIOs, the bundled keyboard and mouse are forgettable and the integrated graphics aren’t built for serious gaming. The small review count so far (three ratings) also means less long-term feedback than the more established picks here.
- Large 27″ touchscreen, adjustable stand
- Copilot+ Ultra 7 with on-device AI
- 2TB SSD — most storage here
- Great shared family machine
- This model is FHD, not 4K
- Low-quality bundled peripherals
- Integrated graphics, not for gaming
- Very few reviews so far
5. Lenovo ThinkCentre M90a Gen 6 — Best for Business

- 【NPU & AI Performance】 Equipped with Intel AI Boost, a dedicated NPU capable of up to 13 TOPS for on‑device AI accelerat…
- 【Display】 The 24‑inch touchscreen delivers FHD (1920×1080) resolution with IPS technology for consistent colors and clar…
The ThinkCentre M90a Gen 6 is built for work that doesn’t stop. Its 24-core Intel Ultra 9 285 is the fastest processor in this guide, and it comes standard with 32GB of DDR5 and a 1TB SSD — both configurable upward to 64GB and 4TB at purchase, which is unusually flexible for an all-in-one. The 24-inch FHD touchscreen runs at 120Hz with 99% sRGB, and the port selection is the best here: Thunderbolt 4, DisplayPort, HDMI, and multiple USB. Add Wi-Fi 7, an IR webcam for Windows Hello, and VESA mount support, and you have a machine an IT department can actually standardize on and scale.
It’s a business tool first, which shows in a couple of places. The FHD resolution is modest for a 24-inch panel next to QHD rivals, the design is utilitarian rather than stylish, and the starting price climbs quickly once you add the upgrades that make it shine. For a stylish home computer this isn’t the pick — but for productivity and expansion headroom, nothing else here matches it.
- Fastest chip here — 24-core Ultra 9
- 32GB/1TB standard, upgradable to 64GB/4TB
- Best ports: TB4 + DP + HDMI
- 120Hz touch, Wi-Fi 7, VESA
- FHD is modest for the size
- Utilitarian design
- Price climbs fast with upgrades
- No-frills speakers
6. Dell OptiPlex 7420 — Best Business Value & Privacy
- ■ Dell 23.8″ OptiPlex 7420 All-in-One CPU ■ 14th Gen Intel Core i5-14500T, 14C (6P + 8E) / 20T, P-core 1.7 / 4.8GHz, E-c…
- ■ Display ■ 23.8″ Full HD (1920 x 1080) IPS LED Alti-Glare Display, FHD Pop-Up Webcam; Intel UHD Graphics 770.
- ■ RAM ■ 32GB DDR5 Memory, 1TB PCIe NVMe M.2 Solid State Drive, No Optical Drive.
If the ThinkCentre is more machine than your office needs, the OptiPlex 7420 is the value counterpart. For around $1,430 it pairs a 14-core i5-14500T with a full 32GB of DDR5 and a 1TB PCIe SSD — a configuration that comfortably handles multi-app office workloads and outperforms its modest price tag. Its standout feature is the pop-up physical privacy camera, which retracts into the chassis when not in use; for compliance-minded workplaces that’s a real selling point, not a gimmick. Wi-Fi 6, DisplayPort, and Windows 11 Pro round out a clean, deploy-and-forget business desktop.
It’s the pragmatist’s pick rather than the showpiece: a standard FHD display, no touchscreen, and a design that prioritizes function over flair. But dollar-for-dollar on business specs, it’s the strongest value in the guide.
- Strong specs for the price: 32GB/1TB
- Pop-up hardware privacy camera
- Fast i5-14500T for office multitasking
- Windows 11 Pro, business-ready
- Standard FHD, no touch
- Utilitarian design
- Wi-Fi 6 (not 7)
- Very few reviews so far

How to choose the best all-in-one desktop in 2026
Pick your operating system first
The single biggest decision is macOS versus Windows, because it shapes everything else. The iMac gives you a polished, tightly integrated experience, class-leading display and speakers, and excellent bundled peripherals — but only in Apple’s world. Windows all-in-ones give you far more hardware variety: touchscreens, higher refresh rates, HDMI-in, more configuration options, and a wide range of prices. Decide which ecosystem your software and habits live in, then shop within it.
Display size and resolution matter most
You’ll stare at this screen for years, so don’t skimp. A 24-inch 1080p panel is fine for browsing, email, and everyday tasks. Stepping up to 27-inch QHD (like the Yoga AIO 27) or 4K makes a real difference for multitasking and any kind of creative work. If you routinely keep several windows side by side, the extra pixels pay for themselves.
Buy the RAM and storage you’ll need for years
This is the rule that separates a good AIO purchase from a regretful one. Most all-in-ones seal their components in, so you generally can’t add memory or storage later. The business machines here — the ThinkCentre M90a especially — are the exception, offering upgrade access, but consumer models are usually locked. Configure for the next several years at checkout: 16GB of RAM is the sensible floor today, 32GB if you multitask hard or do creative work.
Check the ports before you commit
All-in-ones often trim ports to stay thin. Make sure your pick has enough USB-A for existing peripherals and at least one USB-C or Thunderbolt port for the future. The iMac is Thunderbolt-only, so plan on a hub; the ThinkCentre and OptiPlex are the most generously connected here. If you want to plug a laptop or console into the screen, look specifically for HDMI-in — the Yoga AIO 27 has it, most don’t.
Factor in the peripherals and privacy hardware
Bundled keyboards and mice vary wildly — Apple’s are excellent, several Windows machines ship accessories you’ll want to replace. Build that into your total cost. And if you take a lot of video calls or work in a compliance-sensitive environment, a hardware privacy shutter (Dell 24) or pop-up privacy camera (OptiPlex 7420) is worth prioritizing over a slightly nicer spec elsewhere.
