I worked on a system that had five AT class pcs installed near the loading
ramp on an Air Force base.  Heavy exhaust dust accumulated inside (and
outside) all the pcs.  (The first time I saw one, I thought that it had
caught on fire.)  In two years of non-stop usage, I never saw a drive
failure in these units.  Other stuff failed, cards burned out, monitors
failed, power supplies died, but the drives ran on.
