CPUC: I would look into h80i/h100i, since this seems to be a high-end rig with SLI 680s, you should get the best closed water cooling solution which is either corsair or swift-tech
Motherboard: overpriced and unnecessary for a 2 way cf/sli build. There are only 2 good options imo for this build the first being url=http://www.newegg.com/Product/Product.aspx?Item=N82E168...]MSI[/url] followed by ASRock. I lean towards MSI. There is however absolutely no benefit in getting a 250$ saber-tooth outside of aesthetics.
Memory: No problems there but I prefer corsair. I wouldn't go over 1866 as there is positively no performance gain between 1333-2800 but a massive price difference.
Storage: Intel isn't competitive, as Samsung/Plextor/Corsair/OCZz perform much better and are just as reliable(Besides OCZ, I don't trust them) I'd look at Samsung 840 Pro 128GB or Plextor M5P 128GB which is out of stock but in at amazon.
Video Card: I would seriously recommend not SLI 680s because the price is not worth it whatsoever. You can SLI 660 for 30fps less, 660ti for 20fps less, and 670 for 10fps less. Benchmark Sources The 690 is my sli 680 control group if you will.
