I have TWO media pc's in my living room.
One is an XP based box (good gaming spec) so playing NFSMW is quite tasty on my tv
(housed in a Enlight Media PC case *looks yummy*) and the other is in a Micro case (original Tiny chasis)
the other is a juiced up DOS box that plays all the old sckool games that i love like the wing commander saga ... ahhhh such yummyness..... might need to drop the cpu in it though.... (i mannaged to get full DOS support running on a 1.4ghz DDR athlon..
.... its a little quick... but its wholesome for when i play Quake on my TV
