I was thinking of a Koolance Exos 2 its a bit on the high side but I want something external so all I do is have 2 tubes coming inside the case from the PCI slot area into the GPU/CPU and back out to the ALL IN ONE WC. I want it as simple as possible. Does anyone recommend Exos 2 eventhough it's an "investment of sorts". Yes, I know I still have to buy my swiftech for my CPU and my Maze4 for my GPU (I do hope they are compatible with the Koolance)...
