To be honest, I'd start with a single GTX 670 and see if there's a need to go SLI after putting it through its paces. At 1080p there are few games that slow it down
(Since I see only a single monitor in your wishlist). Having the extra slot between the two cards and the side-intake of the HAF will be fine for a SLI setup, though.
Regarding some of the other components...
That MS X4 Sidewinder Keyboard has been great for me, but the keys start to lose their covering very quickly. The result is a mess of bloody-looking keys in the WASD area due to frequent use. Keystrokes are quite loud, too. Great keyboard overall, though.
That ram is a real treat to play with. I had mine at 1866 9-9-9-24 and 1.45v. I could have pushed it to 2133 @ 1.5v, I'm sure.
The Spinpoint F3 is a great HDD, I find it to be a little loud but the performance is spot on.
I'd avoid the HAF 932... it had its time in the sun, but there are other mid-ATX and full-ATX cases out there that'll get the job done while looking a bit more refined and offering expanded features. That's a personal preference, though.
Love the SSD, I have 2 256GB M4s and they are rock solid.
I just wanted to make a few unrequested comments while I was at it
