Hello,
Well I have four computers.
Laptop for being mobile is bulk standard, not for games.
My old games rig, built in 2001 can still play most games but is now used as a server more than anything else.
Extra large case, P4 @ 1.8Ghz, 1Gb ram, 256Mb nVidia 6600, 100Gb H/D, 17" CRT monitor, O/S XP pro.
Mid-range machine, bought in Dec 2006 and up-graded.
eMachines W6409, added ATI300, and 1Gb ram, which makes it a halfway decent machine on the cheap.
Newest rig, built Feb 2007. Xion hydralic case, EVGA 680i motherboard, Intel Dual Core 6600 @ 2.4Ghz, 2Gb ( 2X1GB ) Corsair XMS 6400 matched pair, PNY 8800GTX XLR8, 500Gb SATA hard drive, DVD with Light Scribe, 22" LCD ( 1680X1050 ), Logitech G15, O/S Vista Ultimate.
Hardware in use by more than one machine.
Pinnacle PCTV HD Pro Stick, 3 external hard drives ( 1Tb ), 2 UPS, Linksys WRT300N.
