You could probably change the RAM to 2x8gb sticks just to save some space annd £30ish,it will also allow you to upgrade in the future if you wanted to, unless you specifically wanted to use all the DIMM slots on your mobo. Also, have you thought about the Corsair h100i V2 AIO liquid cooler. My friends have had both the NZXT aio's and the Corsair one and both have said the H100i is far better.It could also save you £25 ish. Apart from that looks like a nice build.
