Old windows 7 laptop what should/could I do with it

I'm trying to figure out what to do with my old Windows 7 laptop. It still works but is slow and outdated, and I want to give it a new purpose or upgrade it somehow. Should I upgrade the hardware, switch to a lightweight Linux distribution, or repurpose it for specific tasks like a media center or a dedicated server? Any advice or suggestions on how to breathe new life into this old device would be greatly appreciated.
