I acquired and old windows xp computer a while ago to play with. First only old versions of browsers are supported. And those old versions will not even play youtube videos. Also a lot of software is not supported. Tax software will not run on anything less than windows 10. So even though the old hardware may be capable of doing what you need to do. The newer neccisary software will not run on XP. That is how they force you to update.
That will run Linux just fine. Be like a new computer.
