Just a couple of thoughts I have, the 1866MHz memory kit may be unnecessary, most would say that 1600MHz is all that's needed but as there's only £2.75 in it i'd go with 1866.
As NeverBackDown says if your thinking SLI/Xfire is likely in the future you'll want to go with an 850watt PSU, either the AX860 or RM850. And if you don't think you will go with SLI/Xfire then drop down to the RM650 and save a bit of your budget for other stuff.
Also if you want to use the Corsair fans in your case and not on the H100i then you will want to get AF120's instead of SP's as they are built for unrestricted airflow as opposed to static pressure.
