Creative ideas for using a Mac Mini G4?

Hey guys,

I have an old Mac Mini G4 laying around, working perfectly fine, and I have no idea what to do with it. My main computer is a super-fast hackintosh that acts as some sort of homeserver as well as my gaming machine and my machine to do work. Then I have a MacBook Pro from 2008 as a backup machine, which also works fine.
I already thought of ripping the Mac Mini and fit one of Intels NUC boards inside, but I still wouldn't know how to use the machine and as it still works I don't want to kill it. It's a cute little Mac
I guess nowadays it's too weak to play 1080p videos smoothly, which means it can't be used as HTPC as well. I don't need some sort of server as well...
I'm not gonna sell it, because I'm not getting back what I paid for it years ago.

So do you guys have any creative ideas of what to do with this little thing?

I have a G4 mini, also. The processor was upgraded to a Core2Duo ~2.something GHz - but isn't recognized as ML capable.

I also have no idea what to do with it.

There is a G4 version of Plex out there. Maybe I can have it drive the TV.

Run MorphOS or AmigaOS on it and impress your friends, boost your geek ego as well.
