I treated myself to a Pioneer 427XD HD plasma, Yamaha YSP-1100 sound projector and SVS SB12+ Sub for the lounge for Xmas. I'd been drooling over a set-up like this for years and took the plunge! Now I'm thinking of getting a PC to go with it seeing as it's got PC input on the panel and more inputs than you can shake a stick at on the sound projector.

However, I'm totally new to Media PC's and not sure what the best option is; to buy one ready-made (are there UK online stores that specialise in these?) or get one built. Who builds these? I want something black and box-shaped that sits on a shelf rather than a tower at the side sat on the floor. I'm after something flash looking like this:

The PC would be used for recording and archiving TV/Movies, storing and playing thousands of MP3's, viewing photo's/camcorder footage, surfing the net, checking email and maybe playing games occasionally. I'd want the keyboard and mouse to be wireless.

Has anyone got any advice/pointers?
