I am interested in building or buying a watercooling system. I don't know to much about this but I do want to start some major over clocking and the sound of a water cooled system sounds so cool to have. I only know of one system case witch is the Koolance Super Liquid Cooled Case. this system looks choice any imput on it or others? also what about water leaks? is this a big problem with some systems or are the parts pretty good? and finally what about the upkeep on them? is there a specail fluid like radiator fluid or just water? thanks for the help.
