1. dont get that radiator, go for the swiftech mcr-220, much nicer overall
2. dont get that gpu block with that pump. Go for either the mp-1 or the silverprop ones. The maze 4 is designed for low flow enviroments, whereas your pump, which i have as well is one of the highest flow available.
3. You need tubing, hose clamps, water additive, t line parts or a reservoir, and fans for the radiator
