No, I'm not. I just discovered it only a year or two back.

This is actually common. I've gotten more than a few S-100 chassis, for
instance, where they've been modified with electrician's tape to imrpove
air flow (IMSAI 8080's usually have tape along the inside vents on the
power supply side so that the fan draws air from the opposite side and
pulls it over the power supply.
On the PC, there are plenty of air intake vents, including the floppy disk
drives themselves (for better or worse).

I have at least one. They are rather rare over here as well.
