Looks fantastic. CPU is great- I'd either go with the 3570k or 8350, can't go wrong with either.
Mobo is good- has practically all the features you'd want at the lowest price point.
HyperX 3K is awesome- can go with most anything there (samsung840, corsair forceGS, ADATA SX900, OCZ Vertex 4, Mushkin Enhanced Chronos, Crucial M4) just pick one on sale.
WD Black is great, so is the blue and seagate barracuda (Only two brands iv'e used and trust).
I LOVE G.Skill ram. You could opt for 1866MHz if its only a buck or two more, not that big of a deal though. If you were going for a really aggressive overclock faster ram helps- but with the extreme 4 and you not wanting liquid cooling, 1600MHz is fine.
The 7970 is super powerful at and yet a great price at the same time. I would try to find a model that had better cooling- gigabyte has the windforce model, msi has the twin frozr stuff, HIS has IceQ, XFX has the DoubleD, Sapphire has DualX- find one at a good price and you wont have to worry about heat issues as much
With the Extreme4 I'd say go with either the Hyper212 or Xigmatek for the cooler, great prices and will net you a decent OC. (Note the Xigmatek has a white LED fan- pro/con up to you)
For the power supply I'd say go with the 850W SeaSonic. High quality and enough power to OC the cpu and gpu comfortably.
I'm a big fan of the Phantom 410 (seems like you either love it or hate it) but just pick one you like. Features to look for are CPU backplate cutouts, USB 3.0 with the MOBO HEADER- not the pass thru's, rubber grommets for cable management, tool-less drive bays, ample fans, and dust filters.
Your comp should rock. All you really have left is aesthetic choices
