We have an in-win q500 full-tower case.

The power supply has a fan blowing out the back.

We added an intake fan in the fan cage on the lower front.

On the upper front we have a bay-cooler drive fan blowing in.

There are two places in the case on the back where we could
mount additional fans: one on the lower half (where the mother-
board and the add-on cards are), and the other on the upper half
(where the power supply and the drive bays are).

If we were to add more fans, I suppose the upper fan should
be an exhaust fan.

If we were to add a fan on the lower back, should it be an
exhaust fan (air blows front to back) or an intake fan (air
blows bottom to top)?

(We have a slot-A athlon with a dual-fan processor heat-sink
on it, and an agp video card that came with a little fan on the
video chip.  In addition, we have a scsi card, a cheap nic, and
a legacy isa sound card.)

Thanks for any explanation of the right way to do this.
