I was figuring I'd just screw it into the 80mm exhaust fan on the back to attach it to the case, so to that end, here are my requirements for material:<BR><BR>1. Light<BR>2.

The 80mm exhaust fan is thermally controlled and supposedly runs as follows: 3,100 @85c; 2,600rpm @ 65c; 2,100rpm @ 45c; 1,800rpm @25c. Good to know, but it doesn't help out much.
