Water cooling Help me please

Solution
There is two types of watercooling, Custom Loops and CLC's (Closed Loop Coolers).

CLC's are what you have found, they come pre-made and all you do is screw them to your case/CPU and plug them in. They give performance about on par with equivalent air-coolers, with something like a H100i being about the level of a NH-D14, usually being $20-30 more. You cant change them, you get exactly what it says.
Custom Loops is where you buy each component (pump, CPU Block, reservoir, fittings, etc) separately and assemble it yourself. Its extremely flexible and performs far above any other common cooling solution. However its expensive, an upgradable CPU loop (that you could easily throw a GPU in later) would be ~$300.
