Group test: what's the best all-in-one PC?

5. PC Specialist PowerGlide Extreme GT640

• Reviewed on: 14 August 12
• RRP: £899 inc. VAT
• Rating:

With uninspiring plastic looks, particularly noisy fans and no pre-installed software, this is no family PC. We feel the majority of users simply wouldn't put up with it. Where the PC Specialist PowerGlide Extreme GT640 scores is in Windows speed, particularly gaming where support for more powerful graphics cards and processors gives it an advantage.

4. Asus E2700INTS

The Asus E2700INTS is a very impressive system which can replace a desktop PC, TV and Blu-ray player with a single, smart and powerful device.

3. HP Z1

A truly impressive feat of engineering, the Z1 features professional-grade build and components throughout. Its tilting, hinged design allows for quick, tool-free maintenance and it delivers excellent performance and superb graphics via its 27in IPS display. The three-year next-day on-site warranty places it in a different league to consumer systems.
