Wow! Nice rig! Don't expect much response the way things are, but i'll give you my two cents.
Honestly, my gamin' PC is an old clunker I got for free after my laptop (which was faster) died several months ago.
Specs are as follows:
Pentium 4 HT 3.0Ghz
1 Gig Ram (THATS ONE THOUSAND TWENTY FOUR WHOLE MEGABYTES ZOMG!)
Geforce 6200 (Suprisingly, this is the first computer I've ever owned with a dedicated videocard)
160GB HDD
17" Dell monitor
Seriously, this thing can *barely* chug through WoW on the lowest settings but it plays classics and emulators just fine which is all I really care about anyway. I will probably build a new rig sometime, but there hasn't been many games in the last few years to give me reason enough to do so.
Anyway, post some pictures of your battle-station when you set it up!
