I don't have experience with the QS, only a G4 Gigabit. They are probably similar. I thought my machine was quite dust free UNTIL I removed the fan assembly (to swap out the power supply). Behind the fan assembly are perforations in the metal chassis which where all blocked up. You have to do quite a bit of dismantling in order to get at them. But I think its worth in. G4 or not to G4? That is the question. John Niven ----- Original Message ---- > >Where does the Quicksilver 2002 bring air INTO the case? __________________________________________________ Do You Yahoo!?
