Mobo / CPU - Z77 is the latest and greatest and has features that are not available on the P67 boards .... it's doubtful however that those features will come into play in the life of the typical system (3 years). The WS Revolution is an expensive board, made so by it's ability to do x16 x16 GFX. While immaterial in most instances, some games did benefit substantially form the extra bandwidth on P67 .... not so w/ Z77.
If ya were willing to spend that kinda money, the board I'd recommend is the Asus Sabertooth Z77....it's an extremely overclockable board, superb OC features and 5 year warranty insures ya won't have to worry about "repair costs" down the road. Nice combo too w/ the 3570k

Cooler - Noc has had a long reign but it's been eclipsed in thermal performance, aesthetics and warranty (5 years vs 1) by the Phanteks

I'd stick with the WD and its 5 year warranty, Seagate Barracuda XT is faster but has 3 year warranty. Seagate Barracuda (no XT) has a measly 1 year warranty and is best avoided.
Can't see the 7870 as a choice with the 660 Ti breaking in two weeks. The Asus 670 TOP is faster than the 680 (999 fps in Guru3D game test suite) and costs ya $0.43 per frame while the 7870's 701 fps (30% slower) comes in at $0.44 frame
As for SSD's the kings of the hill are Sandforce drives w/ Toshiba premium toggle mode flash (Mushkin Chronois Deluxe - $200) the Plextor M3 ($250)and the Samsung 830 ($250)
HAF -932 was great case .... in its day .... but it's long in the tooth and eclipsed by newer designs such as the Corsair 500R

I can't see that price for a PSU that won't let you CF / SLI. These 850 watters will provide the headroom necessary for stable voltages at high overlcocks, low ripple and low noise due to not being poushed to their limits.
