One was plugged up by dust and started smoking and might have set the place on fire if the person using the computer hadn't pulled the plug. There is reasons why I hate setting computers on the floor ... The other one didn't survive a transition from 230V to 110V, though it was rated for that range. > I have a five year old machine that I use for working from home.

You're worrying too much. Those collected parts will most likely go bad through technical obsolescence and not from being used or not used. That is when you have good hardware to begin with, like a nice workstation from HP or Dell with ECC RAM and a Xeon in it. If you don't, you might get a Dell workstation (because it has basically become impossible to get firmware from HP) used off ebay, or even a new one. Then you can still keep your current computer as a fallback. But with a new workstation, you get a warranty ... Five years is not old for a workstation. After about 10 years, they're starting to get somewhat slow. If you're planning to keep one like 5-- 10 years, it's probably better to buy new because it'll cost about as much when you start upgrading a used one. Life is way too short for bad hardware.
