Yowza.
I found two web sites recently where a nice veriety of different types of
useful cooling devices (mostly for PeeCee type systems) are available:
http://www.3dcool.com/
and:
http://www.icedmocha.com/
I bought two ``slot fans'' from www.icedmocha.com recently, and I think I'm
sure now where one of those two fans is going. :-)
