H-100 for ease of assembly and quite frankly the kits from EK are really good, plus theyre upgradable which means if you'd like a waterblock for any specific GFX you can upgrade it, whereas the H-100 is effectively locked down.
So my tip is google for the EK kits and see what you find, otherwise for cpu alone any 1x120 or 2-3x will cool the cpu plenty all the way up to 5ghz+ (if you get a good cpu sample that actually can do 5ghz)
