My Second Build

Solution
I personally do not like closed loop liquid coolers like the h100i. You can get a cheap and quieter air cooler that performs the same.

And yes, the build looks great.
few issues:

The PSU is not good. Change it to a 650w unit from XFX, antec, Seasonic.
No need for 16gb RAM for gaming. 8gb is more than enough and will be for a long time.
Get an i5 not an i7 for gaming.
Use the saved money from the CPU and RAM to get a gtx780. This will give a BIG improvement in gaming performance.
