Yea, for general computing a lot of older PCs are very manageable. I have an old 2008 unibody MacBook laying around that I had to use for a little while a few months ago and it was perfectly usable on mint. Even felt a lot better than a lot of newer machines since apple built them like tanks and their trackpads back then were so ahead of their time they easily beat out a lot of brand new machines.
