The main one with all the multimedia I got back in 2005 is a HP Media Center m1050e with a AMD Athlon64 3200+ (1.8 Ghz NewCastle) single core CTO from Office Depot. I also have another Media Center about a year older running a 3.2 Ghz Pentium 4 with HT (Prescott). Both have TV tuners and and not maxed out on RAM yet. I have probably upgraded the drives on those more with all the media I have, lol. The only downside on those units I see it not running dual core. The one I use the most in my Toshiba Satellite A215-S4757 with the Turion X2 TL-56 running Windows 7 RC 64-bit. This one is pushing two years and I'm probably replacing it this fall.
