I have some criticisms with your build:
1) The 5930K is a waste of money. It's $200 / 50% more expensive than the 5820K, which is the same CPU minus a few PCIe lines. There is no performance penalty for running your video cards in PCIe 3.0 8x rather than 16x.
2) That motherboard is astoundingly expensive. What does it do that a board half as expensive does not?
3) You don't want to raid SSDs, and the 850Pro is an awkwardly priced one at that. It's only very slightly faster than the much cheaper 850 EVO, and very significantly slower than the 950 Pro. Why not go with a single large, much faster M.2 drive? Ditch the old SATA interface for SSDs if you can.
4) The 980 Ti is arguably an old and outdated card now, having been replaced by the GTX 1070 and 1080. The 1070 is faster, $100 cheaper, draws less power, and has a better feature set.
5) 1050w is unnecessarily large for your PC. You have a 140w CPU, and a pair of GTX 1070's are 150w each. You could run your PC safely at stock on a 550w-600w unit, and even a 750w would give plenty of headroom for overclocking.
6) I strongly recommend people away from AIO watercoolers. The Noctua D15 performs just as well, is cheaper, quieter, and it won't leak and destroy your expensive components. It also doesn't have a pump to fail (and all of them DO eventually fail, ask me how I know), and on top of that pumps are noisy and dump more heat into your loop.
