Well I plan to water cool a 4690k and a 1080 vanilla card. I've always wanted to build a water cooling setup so my thoughts are to build it now on my current rig. Then, when the time comes for my to upgrade to something new I'll already have everything I need except a new CPU and GPU water block.
With that being said, I see that XSPC sells a "CPU kit" where I can easily add a reservoir, GPU block and another radiator or two to the loop. Seem like a good plan or should I just piece everything separately?
