Is it possible to build a mining rig for $2000 that includes four 7970's? I would really prefer avoiding the need for riser cards. I'm assuming that that greatly offsets prices because of the need to spend so much of the budget on a higher end motherboard.

I suppose another war of asking would be: Please provide a parts list that includes a quad 7970 build for $2000.

Anyway, I thought I would ask.

Thank you very much, indeed.
