I tried re-ordering everything using this site to help keep things simple.
As for your parts, I have a few other suggestions if you're willing to give 'em a try. The GPU you picked out is currently on sale at NCIX (not newegg) for $350. If you want, you can switch this out for a similarly priced HD 7970. It typically outperforms the gtx 670 in most games. You may be able to get some free games depending on the vendor you buy from.
I picked the Antec 1100 for a case. You're more than welcome to switch it out for the original case you chose. The Antec 1100 has more mounts for fans and a ton of room behind the motherboard tray to store excess cables. This case is also filled with rubber grommets to help assist with cable management. It even comes with front panel USB 3.0. I believe this is one of the best bang for the buck cases out there.
I switched out a couple of other parts. I noticed you stated the price next to the part, but when I clicked on the link, the price had changed for the worse. In other words, if you were to go with all the original parts you had chosen before, you're gonna be paying in excess of $1400.
One more thing, if you do not plan on doing SLI/Crossfire in the future, you do not need a 750w 80+ gold PSU. It's overkill. A 750w 80+ bronze PSU will more than get the job done, but only if you plan on doing SLI/Crossfire. If not, then a 500w PSU would be just right.
