For that matter, I've never heard of a PClone power supply that gets the 
airflow right--they all blindly follow IBM in the matter.  The airflow SHOULD
be drawn in from the outside through a filter, then blown through the power
supply and out through the chassis.  Instead, the power supply uses the 
world's most expensive (and probably least effective) filter: the motherboard,
disk drives, and expansion cards....  And the suggestion I saw recently to
put a filter over the grille on the front of the machine won't help much, as
it will restrict the airflow through the grille, so more air will enter 
through all the other openings, the largest of which are the disk drives....
