Both directions have advantages and disadvantages.

Pushing air into the PS:

     Advantages:  Draws relatively cool (outside) air over the cards.

  Disadvantages:  Draws air through biggest hole (floppy drives)
                  depositing dust over drives and maybe the cards too.

Pushing air out of the PS:

     Advantages:  Allows one to filter the air going into the PS via the
                  back of the computer.

  Disadvantages:  Air that first goes though PS is warmed so the cards
                  don't get as much cooling effect.

Thanks for all the responses!

  Just how much can $1,000,000,000 buy nowadays?

  o  Pay a full year's tuition for 62,500 students at private colleges.
  o  Feed 550,000 homeless people for 1 year.
  o  Purchase 400,000 personal computers for inner-city schools.
  o  According to Dick Cheney, it's the cost *per day* of a war in Kuwait.
     (Of course, not counting the tens of thousands of human lives...)
