I'm a semi-noob when it comes to water cooling, I understand the need for it and will overclock my CPU when I do it. I'm looking to buy the XSPC RayStorm RS360 kit from FrozenCPU, and want to know what the first thing I should replace is. It is going into a Corsair 800D, so th first upgrade will probably be a reservoir inside the case for looks. Any suggestions? Thanks!
