Used to be obsessed with water cooling in an attempt to overclock and have a silent system. Now use a £20 Gelit CPU cooler and decent GPU card custom cooler and my system is silent with a CPU/GPU that doesn't need overclocking and runs silent.
With CPU's and GPU's getting cooler, smaller and less power hungry..... I agree with shaithis, water cooling is not required to achieve overclocks or silence anymore.
Although I do miss the look of tubes and water in my PC.
Also, that demo machine is terrible looking - would have thought they would have spent some time on cable management.
