Yeah... you have a LOT of learning to do my friend. Watercooling is not something for beginners. It takes a lot of planning, you need to know some basic thermodynamics or at least be able to read graphs to know what sort of rads you want with what fans based on air flow rates and noise levels if that's an issue, need to know what sort of pressure drop you might expect in order to pick out a pump. Then you have tubin sizes, fiting sizes, threads and clamps and all sorts of goodies.
Good luck! There's plenty of info out there.
