I have done this.  It was fairly easy.  The fan is a standard size, and 
it had a standard connector to the board in the power supply.  Of 
course, you want to be careful around the inside of a power supply, but 
I think everyone on this list knows that.  In fact, one of the power 
supplies in mine has a noisy fan.  I should look for the replacement as
