I call this the DOOMINATOR...i built it in august to play DOOM 3...ive recently added a 512mb stick of PC-3200ram and the front case mod, along with the lights...
system specs
AMD Athlon XP 2700
ECS KT600-A mobo
ATI Radeon 9600 256mb
220 gigs of HDD (1 60gig and 1 160gig Raid0)
5.1 sound built into mobo
1 gig of pc-3200 ram
it plays doom just fine...loads a little slower than my friends 64bit system..but performs just as well...even with hl2...its my baby...and it loves me..lol
