Good point on the power supply, I'll take a look at that. As for the ram, those 4 sticks are actually on sale now and the price keeps going down. That's why they are included (went from 83,90 to 61,05 and now it's at 54,53).
Why would the H100i be beneficial if i don't have an unlocked cpu? And Win10 pro is actually cheaper than home on kinguin (I don't know why).
