Excellent build. Very good choice. But, IMO, what I WOULD do is,
Change that liquid cooler for a air cooler, something slightly higher than a hyper 212 maybe.
The asus motherboard is slightly overkill, I would get asus mainstream boards, they all do the same thing.
Instead of getting a fan, get a case that comes with fans, might I suggest corsair.
And if possible, get a slightly higher end gpu with the money you saved, like a 7950
