800Watt PSU for that system is a waste, rather get a 550/600W.
Get a HD7850 or a GTX 660 atleast, your GTX 560 is a good card if you plan to keep it below 1080p resolutions.
Also recommend Std. DDR3-1600 it's R600 for 1 8GB stick of Corsair Value Select, as opposed to your choice of ~R900 a stick.
Unless you plan to OC (which you are) I think that H100i is overkill get something like a Coolermaster Hyper T4 CPU Cooler can get very good air coolers before you go with liquid cooling.
Although this is all just my constructive criticism take it or leave it.
