Don't bump the thread so much, you make people less likely to help you, its 7AM in the US east coast, and still 4am on the west. I have to head out for work now, but I'll be back in a few hours, if someone hasn't put a build together by then, I will.
I didn't include an optical drive in the build, since really its hard to screw that up. Pick any old DVD-RW drive. The 7970 is currently the strongest gaming video card on the market, second only 2 the insanely rare and stupid expensive GTX 690 (and 2 7970s crossfired would cost about the same and eat it for lunch)
