I don't have any such old computer or system lying with me and don't like to keep these when I buy new one and mostly sell these to the store from where I get the laptop or computer.

People are not all purchasing new computers once a while, while the computer is still functional then they still use it. For example my computer is still working from 2015 until now with some slowness from time to time.
