6. Lenovo IdeaCentre Horizon

Part all-in-one, part tablet, the IdeaCentre Horizon folds flat into a unique family entertainment system. Build quality is high, but connectivity is poor and our sample also suffered from poor hard drive performance.

This space-saving all-in-one PC delivers excellent application performance, but lacks a discrete graphics chip for gaming. It's not as attractive as most and requires some self-assembly, but offers good features and value for money.

4. MSI Wind Top AE2712G

This is the least expensive 27in all-in-one PC we've reviewed of late and offers a correspondingly lower specification with somewhat lacklustre performance. The nVidia graphics are particularly disappointing. However, you do get a Blu-ray player and a built-in tuner with the MSI Wind Top AE2712G.

This is a basic, no-frills all-in-one with adequate performance, no Blu-ray drive and no touch screen. However, at this low price, it represents excellent value for money and even comes with a built-in Freeview tuner.

The Dell XPS 2720 is undeniably expensive, but delivers incredible performance, excellent features and offers a truly awesome 27in Adobe RGB touchscreen display. Next-day in-home support from Dell will make a huge difference to those relying on their PC for business.

1. Apple iMac 27in (Late 2012) Ultimate

The 27in iMac is still an obvious choice for any creative designer. It's immensely powerful and delivers outstanding image quality. It also offers peerless design and impeccable build quality. This model is by far the quickest for running games, although there's no touchscreen for finger navigation in Windows 8.
