reading is the cheap and easy part of water cooling, wait till you spend a day installing a loop, getting it leak tested, bleeding the stupid thing only to have the rig go straight to overheat and shut down.
spend another day draining the loop, pulling the whole rig down, building it out of the case to test it only to find you either mounted the rad fans push/push or forgot to take the protective film off the water block.
of course I have never done either of these.................
