The 'Wind Tunnel' G4's were very early Mirror Drive Door models, and the fans 
were REALLY loud, Apple instituted a free power supply/fan replacement program 
along with a firmware update that tamed the noise. This did NOT apply to any 
other model.

There were very few of these systems actually released to the public before the 
fix was initiated; and the publicity and Apples quick response 
(uncharacteristically quick) meant that an unmodified loud one is quite rare. 
(and getting rarer along with all the G4 models)
