I have a Antec 1080AMG (
http://www.antec-inc.com/pro_details...p?ProdID=91082) with 5 Fans and I have to say it is pretty noisy. That water cooling system suggested by unicorn looks pretty cool. So DoG, you don't need to mess around with heaps of power cables for the fans.
Btw, how efficient you think these water cooling systems are? How about a rough idea of temperature drop? (compared to traditional fans). E.g.
At CPU 0%: With Fans: ?? degrees Celcius. With water cooling: ?? degrees Celcius.
At CPU 100%: With Fans: ?? degrees Celcius. With water cooling: ?? degrees Celcius.
