Finally decided on a build, in addition to this in the future will be a 1070 graphics card (or 980ti depending on prices). And an m.2 pcie 4 hdd.
Case not required and fans will be bought elsewhere once I've done some measuring and further destruction of my custom case!
I just want to make sure it will all work together and give me decent fps in games (battlefield and racing are the main types) and I haven't added something that is notoriously rubbish.
Edit: forgot to say one of the 1tb hdd will be temporarily used in the ps4.
Cheers
