Apple Mac Mini A1176

What can I do with this old mini? Can I have it updated? Is it worth it? And where would I do something like that? Also, this came from my old business so I have all the operating cd’s I believe. And it was upgraded to be able to switch from from the apple processor where you use safari to also be able to use windows. I don’t know if that’s a good thing or not.

Please advise!

Thank you,
