The others are right. My suggestion: go to 2way SLI using GTX980 cards. Drop the arctic silver, the compound that comes with the cooler is good stuff. With that you can get away with, easily, a 1000watt psu and still be way overpowered. (http://www.newegg.com/Product/Product.aspx?Item=9SIA24G28N1703).
That AZZA case looks very nice and has good airflow, but you might want to consider this Cooler Master:http://www.newegg.com/Product/Product.aspx?Item=N82E16811119260
You won't need extra fans with it. (Buy where you can find the best prices and shipping, I use Newegg for illustration)
Those changes should give one heckuva performing system for about the price point he want to spend.
