I'm about to take the first step into the world of water cooling after i do my upgrade and i'm looking for an easy, newbie friendly water cooling kit. Right now im deciding between Nautilus 500 and Swiftech H20 220 Compact (not the Ultra version, the cheaper one). Basically i need a question answered about the Nautilus 500 to help me make a decision. Can i replace the CPU water block on that kit with the one of my choice, like a D-Tek Fuzion or a Swiftech GTZ? Also i'd like to replace the tubing as well with a Tygon or a Feser UV? Is it possible? I read a couple of reviews of it and it seems that it could be taken apart but i want to make certain that i can use non-Corsair parts with this kit if i wind up getting it.Anyone?
