A 6600K and only 8GB of RAM might be better. Also in terms of raw performance the R9 390 is a better card, and slightly cheaper. Unless you care about nVidia only special technologies. And unless you are future proofing, you probably dont need a 1000W power supply, although you might just be preparing for sli down the road. And in terms of a case, i like DIY-PC cases because they have no branding on them, which is great since I built the pc, not them.
