Fan controller is mainly just because of the geek in me I also was going to 7V mod the fans, but still wanted to run them on full blast if the fancy takes me, and the controller provides this with the minimum of messing about.
The watercooling was mainly just for the challenge as I've done loads of air-cooled rigs now; partly for the noise (my current rig has 5 80mm fans, 2 40mm ones in a drive-bay, plus the CPU, northbridge and graphics card and sounds like a helicopter) and partly so I can see how far I can push the overclock. This also makes the fan controller handy as I can switch between 'for the power' and 'for the noise'.
It will always mainly be 'for the lulz' though
