What makes a good AIO?

 A good AIO should perform well in every area, whether it's cheap or at the very top of the tree. We expect clear and bright screens, good office application performance and quality audio. We also pay special attention to their supplied keyboards and mice, as these can be an area of real compromise.

This astonishing AIO is the best we’ve ever tested, with a powerful quad-core processor combined with a dedicated graphics card and a stunning screen. All this comes at a price, but if you’re in the market for a top-spec PC for editing photos, videos and other media, this PC is actually quite good value. Our only real complaints are the so-so keyboard and mouse that are unbefitting of such a premium machine.

This stylish AIO comes in two very different specifications and can vary in price by up to £300. We’ve listed the more expensive Intel model here, but if you don’t mind more sedate performance you can look at the cheaper model that could save you up to £300. The budget model has a slower DVD writer and boots slower as well. Beyond that, both models have an excellent screen and decent speakers making both models worth considering.

This big AIO will stand impressively on any desk, with a stylish stand and bright touchscreen. You get a mid-range Intel Core i5 processor for good office work and photo-tweaking performance, and there’s even 16GB of high-speed SSD storage to keep the system running in a sprightly manner alongside the 8GB of Ram. A great buy for someone who wants to spent a little more without verging into iMac price territory.

A top-spec all-in-one with a design to match, thisbig-brand model is a sure-fire iMac rival. With a powerful quad-core processor and dedicated graphics this is a proper powerhouse. We were also impressed by the screen and even its built-in speakers are excellent. Our only disappointment is the lack of DVD drive and a rather shoddy webcam.

Of the AIO PCs on this list, this is perhaps the best value. Its mid-range price belies its good performance, great screen and attractive design. Not only that, this machine comes with an SSD and hard disk combination, meaning you get a perfect mix of fast boot times and large storage capacity. It might only get a relatively sedate dual-core Intel Core i3 processor, but it’s perfectly usable for basic office and web browsing tasks. The only downside? The rather disappointing speakers.

We test all-in-one PCs more thoroughly than any other organisation

We've put hundreds of PCs through our independent lab test. We check the screen and sound quality to make sure you’ll get the most from films and TV; we measure colour accuracy and brightness for the screen, plus frequency response from the built-in speakers. 

We also test the bundled keyboard and mouse that come with the PC - are they wired or wireless models? Does the keyboard feature an irregular key layout or size, plus is the mouse comfortable to use for long periods of time? We're sure to leave no stone unturned.
