That's a fantastic build! Some fine tuning -
Get 1866 cl9 1.5V ram instead - only a few dollars more
The Corsair RM is in Tier 2a of http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html.
Get a Tier One power supply instead eg Corsair AX 860, EVGA Supernova 1000, Antec HCG Pro Platinum 850M
