NOTE: this is all from before the other 2500K posts
Get a cheaper, 750W PSU. Here's a fantastic model from NZXT:

You MUST go 2500K, not 2500. That is not an option. Overclocking is easy and safe, and you'll need some to handle the 7970, let alone the second that you'll get sometime in the future. If you can get to a physical Microcenter, it's $180.
Get some shorter RAM. Those Vengeance heatsinks don't do anything, and they may get in the way of your cooler when, some day, you feel like filling up your slots.

I think you could do with a CPU heatsink that's a little tougher, like a $50
Scythe Mugen 3, but the EVO would do fine.
Yeah, you could definitely do with a cheaper hard drive. With an SSD, the speed won't matter much. 1tb Caviar Green, $110:

Choose your case by stylistic preference, and don't feel like you have to spend more than $60. Go for the 932 if you like its look, but there are lots of other, cheaper options.
I'd replace the mobo with an MSI Z68A-GD80, $190:
