If you want to do all that then buy better hardware... watercooling doesn't do anything but give you a little more performance out of your CPU....and yea.. it makes no noise.. Alot of people here including me will get higher 3dmark06 scores than you and it makes no difference! as long as you can play the games you want to, who cares?
ask "the watercooling guru" for info on those other setups... though you don't need to watercool your GPU's I overclocked mine I am not kidding as high as I could possibly get it without physically breaking it and turned the stock fan on high and it performs well but after 4 hours in Crysis it gets too hot.
There is no way in heck you will ever need that kind of power and you do not need to watercool your GPU's.. you can overclock them reasonably perfectly fine without them overheading the slightest bit!
Plus your GPU's I hear you are getting TWO!!!! in SLI!!!!! for God's sake man!!! that is more than enough power to Kick the living heck out of anything you put up against them EXCEPT maybe Crysis.. and if you wanted to own Crysis go out and buy two 9800GX2 cards...
