Best All-in-One PCs 2026

All-in-one PCs have quietly gotten very good. The category used to be easy to dismiss. Underpowered hardware stuffed behind a screen, priced like a premium product, with the upgrade path of a laptop. That description doesn't hold for the best 2026 models. The Apple iMac M4 delivers genuine desktop-class performance in a genuinely beautiful package. And the Windows side caught up, with Lenovo in particular bringing a large FHD display and a strong CPU to a price point that actually makes sense.

If you're setting up a home office, upgrading from an aging tower, or just want a clean desk without a separate PC box and monitor, an AIO is worth a serious look right now.

Quick picks at a glance

Best overall: Apple iMac 24-inch M4

The iMac M4 is still the gold standard for all-in-one desktops in 2026. That 4.5K Retina display has been the best panel in the category for years, and the 2024 model with M4 hasn't changed that. What has changed is the performance. The M4 chip with 8-core CPU is meaningfully faster than the M3 it replaced, and the unified memory architecture means 16GB goes a lot further here than 16GB of DDR5 would in a Windows machine.

The design is the other thing. Apple's AIO form factor has been refined to the point where the bezels, color options, and tucked-away cable management make it genuinely pleasant to look at and sit in front of. If you care about your desk setup aesthetically, the iMac M4 is in a different league from Windows competition.

There are real tradeoffs. You can't upgrade the RAM after purchase, and the 256GB base SSD will fill up faster than you think if you're doing any kind of creative work. The 512GB config is the smarter buy for most people. It costs a couple hundred more on top of the $1,424 this 256GB model is going for, but you'll be glad you paid it at year two. And if your workflow is Windows-dependent, the iMac isn't your answer, though Parallels Desktop handles the occasional Windows app reasonably well.

For home office, creative work, or anyone who spends most of their day in a browser and productivity apps, the iMac M4 is the best AIO money can buy.

Best Windows AIO with AI: HP OmniStudio 27 Next Gen AI PC

The HP OmniStudio 27 is HP's answer to what a modern Windows AIO looks like in the Copilot+ era. The Ryzen AI 7 445 is a legitimate Copilot+ processor, with a dedicated NPU hitting the 40 TOPS threshold Microsoft requires. That opens up on-device AI features in Windows 11: Recall, real-time Cocreator, live captions, and translation features, all running without taxing the main CPU.

Honestly, the AI features in Windows 11 are still maturing and most people won't use them heavily in 2026. But the CPU itself is solid. Running on AMD's Zen 5 architecture, the Ryzen AI 7 445 handles productivity workloads, video calls, and light photo editing without issue. Integrated Radeon 840M graphics aren't gaming-class, but they'll handle some casual titles and are fine for anything that isn't GPU-intensive.

The 27-inch FHD display is the main thing to sit with before buying. 1080p on a 27-inch panel means about 82 pixels per inch, which isn't sharp by modern standards. For distance viewing in a living room or conference room, it's fine. For close desk work, you'll notice the pixel density, especially if you've used a high-DPI screen like a MacBook or the iMac's Retina display.

Price is the problem right now. This machine has climbed to $1,294.26, which puts a 27-inch FHD Windows box within $130 of the iMac M4 and its 4.5K Retina panel. You still get a genuine AI-capable chip, proper USB-C connectivity, and HP build quality, so buy it if the Copilot+ NPU is what you specifically came for. If it isn't, the Lenovo below does the same job for half the money.

Best value Windows AIO: Lenovo IdeaCentre AIO 27

At $699.98, the Lenovo IdeaCentre AIO 27 is where the price-to-performance math gets interesting, and it is now the cheapest machine in this roundup by a wide margin. The Core i7-13620H has 10 cores (6 performance, 4 efficiency) and boosts to 4.9GHz, which is a lot of CPU for a machine in this price range. It outpaces most ultrabook chips you'd find in laptops at the same cost.

Lenovo's 5MP webcam is a genuine differentiator. Most AIO webcams in this price bracket top out at 1080p with mediocre optics. The IdeaCentre's webcam handles video calls well: face tracking works, low-light performance is decent, and the hardware privacy shutter is a must-have on any work machine. The Harman audio system is similarly above expectations. Two speakers and a subwoofer that doesn't sound like it belongs in a laptop.

The knocks are real though. The 27-inch FHD display has the same pixel density issue as the HP OmniStudio. 82 PPI is usable but not great for close-up work. And the non-adjustable stand means you're relying on your chair height or a monitor riser to get the screen at the right eye level. For a setup used 8 hours a day, that matters more than it sounds.

If you need a capable Windows AIO under $700 for general productivity, the IdeaCentre is the one to get.

Best desktop-CPU AIO: MSI PRO AP272P

Here's the thing about the MSI PRO AP272P that most reviews skim over: it has a Core i7-14700, a 20-core desktop processor, not a mobile chip. Every other Windows AIO on this list uses a mobile CPU (chips designed for thin laptops). The i7-14700 is the same class of chip you'd drop into a tower desktop.

In practice, that means the AP272P dominates the raw CPU benchmark numbers in this comparison. For tasks that peg the processor hard (video encoding, compiling, batch processing), it's in a different tier from the competition. The tradeoff is heat and power. MSI's cooling solution is more robust than competitors here, and you can hear the fans at full load. For a machine sitting on a desk, that's entirely fine.

The 1TB SSD is the most storage in this roundup, and the three-year onsite warranty (a technician comes to you) is something MSI includes that the Apple Store and Dell's support lines don't match.

Price is the catch, and it is a big one. At $1,305.29 the AP272P sits only $119 under the iMac, so it isn't a budget machine. Integrated Intel graphics keep it out of contention for any GPU-intensive work, and the 27-inch FHD panel has the same pixel density issue we've covered with every other Windows AIO here. Buy it if you have a genuinely CPU-bound workload and want a desktop-class 20-core chip in an AIO chassis, because nothing else here offers that. If you are shopping on price, the Lenovo is the machine to look at instead.

What to look for in an all-in-one PC

Display resolution matters more than you might expect

On a laptop, you're typically 18 to 22 inches from the screen. At a desk, you're probably 24 to 28 inches away. The difference in viewing angle means display pixel density is less critical than on a device you hold close to your face. But "less critical" isn't "irrelevant." The 27-inch FHD displays in this list run at 82 PPI, which looks fine at arm's length but shows individual pixels if you're working up close.

If you'll be doing detailed design work or reading small text for hours, the iMac's 4.5K Retina (218 PPI) or any 4K AIO panel is worth the premium. For general productivity, 27-inch FHD is genuinely fine for most people. Try to see one in person before buying if you're on the fence.

Mobile vs. desktop chips: it matters more than the model number

The chips in the HP and Lenovo are mobile processors. The MSI uses an actual desktop processor. This shows up in sustained performance because a desktop chip under load stays at its rated speed. A mobile chip running in an AIO chassis may throttle sooner when the thermal headroom is constrained.

For light workloads it's a non-issue. For sustained heavy tasks, the MSI or the iMac (which uses Apple's own well-cooled silicon) has the edge.

Upgradeability is basically nonexistent

Most all-in-one PCs don't offer practical upgradeability. RAM is often soldered. Storage is user-replaceable in theory but voids warranties in practice. And the display is obviously fixed. Buy what you need now, then add another 20 percent for two years of storage growth.

One exception: some Lenovo IdeaCentre configs have accessible RAM slots. Check the specs before buying if expandability matters to you.

Connectivity and ports

A desk-bound AIO tends to be the hub for everything else. Check the port layout before buying. You want at least two USB-A ports for peripherals, one USB-C (Thunderbolt on the iMac, USB 3.2 on the Windows picks), HDMI out so you can plug in a second monitor, and a headphone jack.

Most AIOs lack a built-in SD card reader, which is annoying if you shoot photos. Budget for a USB hub with SD if that's part of your workflow.

Frequently asked questions

Is an all-in-one PC worth buying over a traditional desktop?

It depends on the use case. If desk space, cable management, or aesthetics matter, an AIO wins. If you want maximum upgradeability or a dedicated GPU above the entry level, a traditional tower is still better value. For most home office and productivity use, the 2026 AIO lineup is genuinely capable and the desk simplification is real.

Can you game on an all-in-one PC?

Light gaming, yes. The MSI's integrated Intel graphics can run 2D games and older 3D titles. None of these machines will run Cyberpunk 2077 at high settings. For serious PC gaming, a discrete GPU tower is the right tool.

Which is better for home office use, iMac M4 or a Windows AIO?

The iMac M4 wins on display quality, performance-per-watt, and build quality. Windows AIOs are better if you need Windows-specific software, IT-managed environments, or want to keep costs under $1,000, which today means the Lenovo IdeaCentre at $699.98. The Lenovo is the closest Windows competitor to the iMac's value proposition. The HP and MSI have both drifted past $1,290, so they no longer make the budget case for Windows at all.

How much RAM do I need in an all-in-one PC in 2026?

16GB is the minimum for comfortable multitasking in 2026. For photo or video editing, 32GB is worth having. On the iMac M4, 16GB unified memory goes further than 16GB of DDR5 in a Windows machine because of how Apple's memory architecture works. On Windows AIOs, prioritize 32GB if your budget allows.

Can I use an external monitor with an all-in-one PC?

Yes, most include at least one HDMI output. The iMac M4 supports up to one external 6K display via Thunderbolt 4. The MSI has both HDMI in and out for flexible setups. Running two screens with an AIO is common in home office configurations.

What is the typical lifespan of an all-in-one PC?

Five to seven years with normal use is realistic for a quality AIO. Apple tends to support macOS updates for 7+ years, which gives the iMac a longevity edge. Windows AIOs from HP, Lenovo, and MSI all see 5 to 6 years of useful life before the CPU starts to bottleneck modern apps. The MSI's 3-year onsite warranty gives it a maintenance edge over the competition.

Bottom line

The iMac M4 is the best all-in-one desktop you can buy in 2026. If you're in the Apple ecosystem or open to macOS, $1,424 gets you a display and performance package that nothing on the Windows side matches, and the Windows machines that now sit within $150 of it look worse for the comparison. For Windows users on a budget, the Lenovo IdeaCentre AIO 27 at $699.98 is the clear value leader and the only genuinely cheap machine here: strong CPU, a good webcam, and decent audio without cutting corners where it matters. MSI's PRO AP272P at $1,305.29 is now a specialist buy rather than a bargain, worth it only for raw CPU throughput and the warranty that comes to you. HP's OmniStudio 27 at $1,294.26 is hard to recommend at that number unless the Copilot+ NPU is a requirement.

Pick based on your OS preference first, budget second, and workload third. There's a solid AIO for every use case in 2026.
