I've got to admit here. I think there's a new champ on a PC case price/performance wise.
CASE: Cooler Master HAF 922 $90 (Amazon) (3x 200mm fans!) Intake - Front, Side, Bottom / Exhaust - Rear, Tophttp://www.amazon.com/gp/product/B0026FCI2U
Extra Fan: Cooler Master 200mm fan $18 (Amazon)http://www.amazon.com/gp/product/B002LE8BJA
That case will have 3x 200mm fans and one is DIRECTLY above the GPU's. Plus, another 120mm fan. It also fits any size GPU.
I challenge anyone to find a better case and fan for that price.
