Personally though I think CPU's are way too fast nowadays. A Hush PC could handle everything I do on my Pentium 4 3.06 Ghz setup currently. And it would look cute and not at all out of place next to my Plasma TV.
In fact if anything I would get more use out of it as I would use it as a PVR too, and also the CD / DVD drive would get a lot more use. For TV / Video work you dont need a super hot graphics card.
I am intrigued though, what use do you put your beats of a machine to? 3D modelling work? Any major ass-kick games out there that demand such performance? That is probably where a HUSH pc would fall over latest games, though it would meet 90% of current games requirements (all need direct X 9.0b + P III 700 MHz +), it wont have much shelf life.
For me I am not too fussed my XBox is about for that kind of nonsense.
