I started doing maintencance on computers and other electro/mechanical equipment back in 1964. You'd not believe some of the messes I've seen. One of the worse was a PPG glass factory. The floors and everything else was covered with a dusting of ground glass. That's
REALLY bad for computers and printers.
Here's one Home Computer that I actually documented:
View attachment 1101 This was the grill over the one and only Case Fan.
The rest of this PC was just as bad. This was another PC that was sitting on the floor. Things got so hot inside the case, that the motherboard shot craps. (failed, totally).
This fan sat in the front of the case, right behind the front panel. When I pulled that panel off, a huge wad of dirt fell out on the bench.
Another shot, of the same PC.

More neglect! This PC was toast!
PC's are designed to run a very long time, if properly maintained.
I have several PC's here, that are over 15 years old, that still run like new.
Cheers Mates!
