I've been thinking about getting a media-center type PC, and it occurred to me - would it be possible to cram the necessary hardware into a DIN form factor (possibly double-DIN) without it melting, so one could also have it in the car? I suppose one would need:
256 MB RAM (maybe 512?)
120GB 2.5" HDD (x2?) (1.8" HDDs?)
TV tuner (analog? DVB-T?) (twin tuners for watching 1 channel while recording another?)
Much faster CPU
Sound chip able to support 5.1 (7.1?) output
Graphics chip able to support HDTV playback
Cooling system (heatsinks? fans? liquid heat exchange?)
DVD recorder (pushing it a bit now, perhaps!)
Linux! (already being planned here:
