Best All-In-One Computers of 2026

If your working day is a spreadsheet on the left and email on the right, the Dell EC27250 is built for that desk. The 27-inch FHD IPS panel is rated at 99% sRGB inside a narrow border, so two windows sit side by side without either one feeling squeezed, and Wi-Fi 6E handles the wireless side. Behind it all is a 10-core Intel Core 5 120U with 16GB of DDR5 memory and a 512GB SSD.

What sold us is the stand, which has a shelf cut into it so the keyboard slides underneath. After a week we stopped noticing the keyboard at all — it simply disappeared when we pushed the chair back — and that's a small idea we wish more of these machines copied. The 5MP IR camera with HDR is the other detail we appreciated, because a dim room is where most webcams fall apart.

Two things worth knowing. The panel is 1920 x 1080, and that isn't much resolution spread across 27 inches: text is fine, but comparing photographs side by side looks softer than it does on the iMac. At 13.6 pounds it also stays where you put it. Neither matters for office work, and both matter if you were quietly hoping this would double as an editing station.

The IdeaCentre 24 is the least expensive machine in this roundup, and the specification list doesn't read like it. A 23.8-inch FHD IPS panel with 99% sRGB coverage, a 512GB solid-state drive, Wi-Fi 6 and Bluetooth 5.2, plus USB-C and Ethernet — that's a serious set of numbers for budget money.

We point students and first-time desktop buyers here without hesitating, because the money went where it shows. The screen matches the 24-inch Dell on size and color coverage, and the storage matches it too. What you give up is processor headroom: the Intel N100 has four cores that boost to 3.4GHz, which is comfortable for browsing, documents, streaming and a video call at once, and uncomfortable the moment you open a folder of raw photographs.

The part we didn't expect at this price is room to grow. It ships with 8GB of DDR4 and supports up to 32GB, so it doesn't become a dead end the way a soldered 8GB machine does. The one figure to note is brightness: 250 nits is fine in a normal room and struggles against direct afternoon sun, so think about where the desk faces before you commit.

At 21.5 inches and 11 pounds, this is the smallest all-in-one here, and the one for a hallway nook, a guest room, or the corner of a kitchen where a tower has no business being. The listed dimensions are 6.69 by 19.43 by 15.07 inches, so it slots into gaps a 27-inch panel can't, and the anti-glare coating on the FHD screen earns its keep when the desk faces a window.

What we like most is that nothing about the basics feels like a compromise. Eight gigabytes of DDR5 is current rather than last-generation memory, Windows 11 Pro comes preinstalled — worth having if you use Remote Desktop or drive encryption — and setup is the usual short cable-and-account routine. Then there's the 128GB SSD, which is where the price shows: Windows takes its share and a photo folder or a few years of documents fills the rest. Add an external drive or lean on cloud storage from the start, and keep this one for email, browsing and documents, where it's genuinely pleasant.

This is the Dell EC27250's smaller sibling, and the first question is whether 23.8 inches is enough. The screen comes from the same family — FHD IPS at 99% sRGB with ComfortView Plus — and it sits on the same white stand, just scaled down. The processor steps down too, to a six-core Intel Core 3 100U that boosts to 4.7GHz.

The rest of the package is generous. There's a memory card reader, which matters if you're pulling files off a camera, plus two HDMI ports, a 5MP IR camera with HDR, and a pair of 5W Dolby Atmos speakers. At 12.3 pounds it's easy to reposition, and setup is the same short routine we went through with the bigger model.

The configuration you order is the configuration you keep. Eight gigabytes of DDR5 is the listed maximum, sitting in a single slot, so there's no adding memory in two years when a browser update makes everything sluggish — and at this price that's hard to accept when the 27-inch model doubles it for not much more. If your desk genuinely won't take a 27-inch panel, this is a well-made compromise; if it will, the bigger Dell is the better buy.

Thirty-two gigabytes of memory and a 1TB solid-state drive in an all-in-one is unusual, and it's the reason to look at this HP at all. Nothing else in this group comes close on either count. Behind it sits an eight-core AMD Ryzen 7 7730U, and in front of you is a 27-inch FHD panel with an ultra-slim three-sided border and a 90% screen-to-body ratio.

Around that core, HP has fitted what a video-call machine needs: a tiltable pop-up privacy camera, dual array microphones, and video controls for muting and framing. The white minimalist stand suits a living room more than an office, and at 14.2 pounds this is the heaviest pick here — a two-hands job when you move it.

Whether we recommend it comes down to nerve. A heavy multitasker with a dozen apps open feels the difference 32GB makes, and 1TB means a photo library doesn't need an external drive hanging off it. But this is also the machine in this group with the weakest reliability record: units can shut down, freeze, or refuse to wake from sleep, and a generous spec sheet doesn't make up for a desktop you can't count on. If you want the memory anyway, buy where returns are simple and run it hard through the first week.
