As for buying it for a gaming rig, I would say its worth under $500.
Would you mind finding me one with specs like the OP posted?
I could build a machine with better specs for $500. The problem with someone selling a machine like the one OP is talking about is that usually the seller is equally delusional and overcharging.
Alright then, build me one. I will escrow $600. You will get to keep the extra $100
Deal?
Also, OP how much Gigs each hard drive was? You failed to mention that.
