Dust is the big PSU killer (and UPSs too). I know that in the hospitals plaster room the PC's PSU is replaced about every 6 months.
And twin PSUs have problems too, the other day one blew and tripped out the UPS. Well at least all I had to do is boot, recover filesystem and then database. This 5 yr old server has had 3 'new' PSUs in the last year! Are there PSUs designed for dusty environments?
