PC form factor

Those perforations which many people ended up using for an additional
speaker were actually intended as a feeble attempt at encouraging airflow
through the vertically mounted cards. Those, if you remember, were
full-length back in those days, and because of that fact would have
benefitted had there actually been enough pressure difference between
outside and inside to cause the air to flow substantially.

IBM had people who were really worried about noise, hence wouldn't put a
meaningful fan in the box. That little thing in the PSU (which dies more
often than any other single component in any PC) won't move enough air to
cool things much. It will move enough air to load everything in the box
with dust, though.
