I am new into watercooling and so these kits from alphacool, http://www.aquatuning.us/water-cooling/kits-und-systems/?p=1&f=210%7C2025&sSort=5 looked like the way to go. There is five of them and most look very similar, So I don't know which one to get. Can someone clear up the differences and help me decide which one to get?
