i usually go with a open frame(by the look of that site it seems that you want a standard gaming rig to mine..), h81 pro btc, g1840, 8GB ddr sniper, 120GB ssd, rm1000i and 6 x risers
then you simply choose nvidia or amd
I dont think that website actually sells half of that stuff, because its older, im looking for new parts, i already have frame and risers in hand
