We have seen quite a few different media center PCs here at Geeky Gadgets, the latest one is this cool ultra thin media center PC from Piixl, the Piixl EdgeCenter.
The Piixl EdgeCenter is designed to be placed behind your HDTV, and it is just 30mm thick so when it is in place nobody will be able to see it.
Only 30 millimeters deep, the EdgeCenter is the thinnest “full powered” Personal Computer ever designed and integrates bleeding edge Audio and Video components to turn any flat TV into an universal, high definition Media Center PC. Whether you plan on mounting your TV to the wall, or just want to get rid of bulky audio/video separates, the EdgeCenter is, as a matter of fact, the least obtrusive home-entertainment appliance ever designed!
The Piixl EdgeCenter can fit TVs from 37 inches up to 70 inches, inside there is a 3GHz Intel Core 2 Duo processor, but you can also choose from a range of other processors which include Core i5 and Core i7 options.
Prices start at about $4,043 for the basic model, you can find more details about it over at Piixl.
