Ah, yes, somehow didn't realise it had place for three fans. Makes more sense now. Don't know what is the purpose of that fan controller, as those fans should be rather quiet already, but I guess it's there for the coolness factor as you haven't really heard of reasonable budget anyway.
Is the purpose of water cooling just cooling or is it for silence like the fans?
If the latter, you could think water cooling your GPU. Now then you'd have an awesome rig.
