Looks like the lower specced version of the Lenovo A310 posted at Amazon - but £90 cheaper.
Main difference appears to be less ram, smaller drive and lower specced processor.
If quidco or topcashback tracks the price should come to about £392.
Description from site:
The Lenovo A310 All-in-one Dual Core is a PC with the 'wow' factor, and the world’s slimmest all-in-one PC that looks good from every angle. A 21.5" widescreen display uses high-contrast LED panel technology to produce stunning full HD video.
What’s more, an Intel Pentium P6000 Processor enables high-definition video playback. A range of connectors - including HDMI in and out, integrated stereo speakers, USB2.0, FireWire and 7-in-1 card reader, make the IdeaCentre A310 as practical as it is beautiful.
And with Lenovo Enhanced Experience for Windows 7, the A310 ensures fast 'boot-up' and shutdown, richer multimedia capabilities and easy system maintenance tools.
