"...yet he doesnt realize that you can cut out a piece of a womans stocking and stretch it over the fan to filter the dust out. not exactly expensive, nor does it require someone to be a genius..."
Damn, I thought I was the only cheap ass who did that kind of stuff! Works great on the PC fans too. They get pretty nasty after a while though. I've also used the gause bandage wrapping stuff from the drugstore. Stick some strips of Velcro hooks (the stiff strip, not the soft one) on the case and you can stretch the gause across the opening and stick it to them. When it gets a lot of lent on it, pull if off and cut a new square and stick it on there.
If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
