Holy sh*t
Unbelievable farms you have there..
Yesterday I started crunching for GPUGrid and WCG.
My main rig is Q9550 E0 at 3,4ghz with gainward gtx460 1gb gsglh in sli and 4gigs of ram on a evga 780i board.
Currently I have a second computer on the build, htpc one.
At the moment I have Gigabyte GA-MA78GM-S2H rev 1.1 mobo, gigabyte gt220 1gb ddr3 version and some 3gigs of ram.
need to find a suitable case for it, psu and probly gonna get athlon II x4 640..
Money is the thing holding this project back

Here's a pic for you of the main rig
