Better boards (Z77) out there at better prices. Even better, check out Z87 boards in combo with a 4670K Haswell. About the same cost, 7-15% better performance vs a 3770K/Z77 combo. Look to Asus and Gigabyte first......and PCI slots are a waste now.
That video card you selected is........mediocre (diplomacy there). 128bit, 4 gig of DDR3, just no. DJBPace made some good suggestions on video cards, I would add NVidia GTX 660TI to your list. Hard to go wrong on a 7870/7950/7970 though.
Ditto on the power supply. FSP usually makes decent stuff, but Corsair is a really good "bang for the buck" power supply, reliable as heck to.
Hold off on all the extra fans for now.
At this point, a Velociraptor is just overpriced kludge (sorry to all the Velociraptor owners out there). You can get a WD Black for half the price, or make the jump to a proper SSD.
Oh, memory- 2X8gig would be preferable, DDR3 1600, in the 1.35-1.5V range.

Just an opinion.....................................
I am a retired Ford tech. Next to Fords, any computer is a piece of cake. (The cake, its not a lie)
3770K @4.5, Corsair H100, GTX780, 16gig Samsung, Obsidian 700 (yes there is a 700)
