The already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
The iMac is still the best all-in-one desktop on the market. We love the physical design of the system, and the new components on the inside make it very quick. Our only real gripe is the fact it's difficult to upgrade after purchasing, and upgrading at the point of purchase will cost you an arm and a leg
For discriminating ears and eyes, the XPS 27 (2017) all-in-one offers the best combination of features for the money.
A pretty good value wrapped in a classy, well-designed box, the HP Envy AIO 27 will fill your need for a solid everyday PC that you won't need to hide.
The all-in-one Acer Aspire Z5771 desktop PC offers good performance for an affordable price, making it a wise choice for family computing. The absence of a Blu-ray drive and the lacklustre screen means it won't appeal to movie lovers.
Whichever way you look at it, the HP Pavilion Elite m9000 series (m9065.uk-a) is a good PC. Better value can be had elsewhere, but its quad-core CPU, ample memory and thoughtful design helps it stand out from the crowd
The HP Omen X builds a powerful gaming desktop with smart ergonomics into a bold but expensive statement piece.
The IQ500 is the best all-in-one PC we've seen to date. It's the epitome of style, has very useful features and is versatile. The jury's still out as to whether a touchscreen is absolutely necessary, but those who want a compact, fun PC that's a little out of the ordinary should definitely consider it
A winning design and unusually good sound system highlight HP's first-rate reimagining of the HP Envy Curved AIO 34 for 2017.
The Sony Vaio XL302 is a hugely impressive Media Center PC. It packs everything you could want into its large frame, including dual TV tuners and a Blu-ray drive. But for £700 less you can get the very similar, Blu-ray-less Sony Vaio VGX-XL301
The Packard Bell oneTwo L I7526 is a decent option for those who fancy a touchscreen PC with an integrated TV tuner, but don't want to spend a fortune. It offers good performance, inoffensive looks, passable sound quality and a big, 23-inch screen.
The Dimension 5150c is one of the first PCs to use the Intel Viiv specification, and it makes a good first impression. Its BTX chassis almost achieves the Holy Grail of silent operation. Useless at running games, its Pentium D processor gives it strong performance elsewhere, and it is surprisingly inexpensive. Some users will be disappointed at the lack of a TV tuner, but if recording television isn't a priority then the 5150c is a winner in almost every respect
The Lenovo IdeaCentre A720 offers a 27-inch Full HD screen along with a Blu-ray player, powerful internal components and sleek, stylish looks making it a good option for someone looking for a TV-cum-computer for the living room.
The attractive Samsung Chromebox Series 3 desktop turns Google's web-based Chrome operating system into a decent option for low-cost desktop PC shoppers, so long as you're happy with shortcomings such as low storage and an OS that's still teething.
We found the port selection and placement a little irksome, but this 21.5-inch Apple iMac, complete with 3.06GHz Core i3 processor, is a beautifully crafted machine. It offers solid performance and a bright, vivid display.
The "final evolution" of hacker favourite the Raspberry Pi Model B has arrived, adding two USB ports and becoming more power efficient.
No other all-in-one PC can offer touch-based input or an LCD screen as large as that of the HP TouchSmart IQ816. It's hard to deny that those features make this a compelling desktop for families with a place to put it. Weak performance hinders its suitability for work, and it's not the best digital entertainment center, but we recommend this system to anyone looking to get in early on the touch-computing experiment.
One of the most premium-feeling (and premium-priced) of the first generation of VR-ready gaming desktops, the Origin PC Chronos is compact but powerful.
