what about a hydro series water cooler instead of the bequiet cooler you could get rid of three fans in one go
Hehe I think watercooling is great BUT only if you have the time, money and inclination. These all-in-one kits are all very well, but imho they have a way to catch up with high end air cooling.
It's something I would definitely consider when I and have oodles of time, I've built 3 rigs before and wanted some kind of 'challenge' with my next build, but I'd be scared of not being able to get it working and have a dud rig, can't live without a PC!
