This is old(and stupid), but drop cpu to i7 k hex core(vs x), get a cheaper 3 way sli mobo, drop at least 3/4 of the ram(4x4GB is more than plenty) drop one titan(actually, now you would want 3 gtx780ti, or 3 r9 290x custom cooled, or maybe even 3 r9 290 custom cooled or 3 gtx 780 overclocked and custom cooled). Will point out that on that mobo with 4 dual slot graphics cards, you have no room to plug in that asus xonar sound card(not that you need it. mobo audio should be fine unless you are a serious audiophile in which case, where are your high end speakers/headphones?). Don't know why you need 2 512GB SSDs, 2 960GB SSDs and 3 4TB hard drives for gaming, but whatever. If your goal is to run crysis 3 maxed out on those 3 high speed 1080p panels in 3D, I doubt you could do it even with 4 highly overclocked gtx780ti(not enough fps). That makes your 1k water cooling seem a tad less insane.
Edit:guess this is a finished build. Hope you aren't too bummed by the lack of performance compared to what you wanted.
