Good build so far but a few parts could have been changed, also any reason why you chose an i7 4790k? For gaming, an i5 4690k works just as well, the i7 is more for editing work as it doesn't improve gaming performance. Liquid cooling is quite overrated, the cpu cooler which I chose, the Noctua DH-14 cools really well and costs less, also it doesn't have leakage problems because it is an air cooler.
