Looks like an excellent build.
Corsair Force 3 240GB 2.5" SSD $309
The Force GT might be a better choice, if priced very close. Also, if you're concerned about SandForce, you have the Crucial m4, Plextor M3, Samsung 830 etc. as alternates.
DDR3 ram 2133mhz 16GB (2x8) $120
Not sure if such overclocked memory would make a lot of difference.
I'd just straight up recommend the Samsung 830, if you're not going with an Intel 520.
The faster RAM will get you NOTHING but a bigger hole in your pocket- 1600MHz is all you need outside of AMD APUs.
The rest, in order:
Motherboard: only if you need two x8 PCIe 3.0 slots. If you're at 1080p and have no intention of up-sizing, you don't (though it's nice). Get the entry level.
Case: I love mine, just make sure you get the USB 3.0 version or attachment that upgrades it (I had to do this, works great).
GPU: Just ordered one myself, can't be beat today.
CPU: Consider the 3570k, after overclocking there really isn't a difference.
Cooler: there's an 'EVO' version out with an updated fan.
Paste: Your choice, I've stopped using the special stuff (but it's cheap!).
PSU: Waaay overkill. Drop it to a Corsair/Silverstone modular ~650w, and you'll still be good for a second GTX670, with some to spare.
Spinners: Why two spinners? Why the expensive/loud Blacks? I'd just get Samsung Greens and call it good- linear transfers will be in the same ballpark compared to the Blacks, and you might be able to afford a third if you need that much space.
RAM and SSD discussed above.
