Computer-Case
A common issue with desktop cases is the rust and dust collection over time, this is even more of a problem if you live near the sea. Salt Air is the worst, over time any case with a fan will draw in a lot of dust. A yearly service is a good way to have the computer cleaned both hardware and software.
