Basically your built is good enough, I just wanna add several things :
1. The Case is a bit expensive, but if you like it why not. For references, try to consider CM HAF 922, 690II, and Antec 900 II.
2. I prefer to have one of the following PSU brands : Corsair, Seasonic, Enermax, Antec, Silverstone, PPC and Tagan.
3. I have always bad experiences with Powercolor brand, please consider also : MSI, XFX, Gigabyte, Shappire, HIS, and ASUS.
