Nice build. I have the same case and SSD. Regarding the Noctua NH-U14S; how silent is it when you're gaming? When I was doing my build I had to cut cost somewhere since I went for the i7-4770K and GTX 780 (55% of total system cost ) and settled for the Noctua NH-L12. It's 'okay' but it's too loud IMO.
Under 100% load and the overclock I currently use (4Ghz), it gets clearly audible but nowhere near loud. When gaming I think the dual video cards make more combined noise, but overall it's still not very noticeable over the game sound itself.
There's a huge difference between it and the L12. I have the L12 for my living room PC and had to tweak it to the lowest possible RPM available in the BIOS to get it at something tolerable.
