I read a review on this in Home Cinema Choice. OK if not one to set the world alight IIRC.
Based around a HiperMedia Chassis with an ATI RS480 chipset (X300 GFX and tv out built in). There's a distinct lack of upgradability (1 PCI slot occupied by a DVB-T card). AMD64 CPU, and can't remember HDD size
£500 is cheaper than retail. You could probably build one to similar spec for less...all depends if you can be bothered I guess
