Edit: this is sort of a reply/comment to pH's post.

Hehe I own the site, and never will put water into a mission critical machine (unless the MFG has put it in there as part of their spec, and its been run through the high end QA processes by the MFG that puts anything any reviewer, and Enthusiast MFG will ever do for "over the counter" systems). I do work in the world of enterprise IT and the mentality is that fewer points of failure the better. The way I see it water cooling increases the points of failure almost exponentially from a simple HSF and fan. (which most all mission critical machines have 2 or 3 redundant fans on stand by incase one fails.)

Also the rationale is that if its mission critical, you normally can accept that it may be loud... hell servers (real servers such as Dell 6600's etc...) are louder than all hell, at the limits of OSHA work regulations. But their points of failure is so limited and with such redundancy that its a true mission critical machine.

The definition of Mission Critical takes on a different meaning based on who says it. When you work with data systems that service 2 million people... its slightly different than say your home PC.

Now on my home PC, I wont put water cooling in it, because its not needed... I got 2 HSF's 2 80mm slow fans, and slow fans all around. Its stable, fast, and quiet. and far less complex than any watercooling system. (once again to the points of failure).
