I would have kept the CPU and GPU in separate cooling circuits. That way upgrading parts or replacing defective compents in the future will be a lot easier to deal with. Part of the reason I refuse to go to liquid cooling on my graphics cards is because of the sheer asspain it is to deal with the waterblocks and cooling circuits required. I might reconsider watercooling them in the future once watercooling circuits become more user friendly. Add that to the fact that I upgrade my CPU, motherboard, and GPUs at least once every 12-18 months doesn't make watercooling such an attractive upgrade for me either...
