Ok, I looked over some of the parts mentioned and here is the build now. Thanks.
Processor: Intel I5-3570K
Motherboard: Gigabyte GA-Z77X-UD5H
Video Card 1: Gigabyte GeForce GTX 670
Video Card 2: Gigabyte GeForce GTX 670
Memory: G.Skill Ares Series 8GB
HDD: WD Red WD30EFRX 3TB
Power supply: Corsair AX860 860W
Drive: LG Black 14X BD-R 2X BD-RE (wanted a bluray burner)
Cooling: Corsair Hydro Series H100i (wanted water cooling)
Case: Thermaltake Level 10 GT Snow Edition (i like this case...i know it's expensive...just personal preference)
How much is the 3TB wd red ? Because the barracuda is slightly faster, same reliability and cheaper.
I'd get a ssd, it will improve the loading of the games and maps, will boot the os faster, improves the system responsiveness.
With a 2000$ build more or less, a ssd should be included, you can just get 2TB hdd.
Also a quality psu with 750-850 will do for the system(with two 670 GTX).
The xfx is fine, it's a bit overkill, it was from the other list of a suggestion, but it's a high quality psu made by seasonic and modular.
If you want a 750W psu, i suggest the rosewill capstone 750M, it's made by super flower another high quality psu, it's as good as the corsair, but i bet it's a lot cheaper : http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The new ax series seem to have a e high pitch noise or coil whine.
