    This computer's tiny and stylish design means it will fit onto any desk, and the lack of a screen means you can pick exactly the right monitor for your needs. It doesn’t have many ports, and the built-in speaker is poor, but aside from that there is very little to complain about.

    If you’re after a gaming PC, there’s very little not to like here. Just keep in mind that this is a large computer, and that in addition to a monitor you will also need to buy a keyboard and mouse if you don’t have them already.

    This is a great desktop computer that’s fast and has all the ports and connectivity you could wish for. For the average home office user it might be a slight overkill, particularly with the graphics card, but if you want a computer that looks the part and is capable of whatever task you throw at it, it’s well worth a look.

    There’s little not to like about this simple but effective compact computer. The processor has plenty of power, and there’s a wide selection of ports, so it should have everything you need to get you through your daily computing tasks.

    This is a good desktop PC that handles everyday tasks with ease. The keyboard and mouse could be better and it could perhaps do with a few more USB ports at the rear, but beyond that there isn’t much to complain about.

We test desktop PCs more thoroughly than anyone else

Our tests go further than those carried out by other organisations, and because Which? is independent and does not accept advertising or freebies, you can trust our reviews to give you the full, honest and impartial truth about a product.

When we're testing desktop PCs at the Which? lab, we make sure that the tests we're running represent the sort of things you'll be doing with your new PC. So whilst we do the things you've expect, such as benchmarking tests to check how powerful these machines are, we also record how long it takes to boot up, or transfer data from a USB - tasks that we all do everyday.

To discover the benefits take a join Which? and you'll receive access to all our online content.
