I have a IIIXe (very similar to the one in OP) somewhere. Really limited in what it could do, but very cool for the time. I also have a later model Zire somewhere that had enough horsepower (with a mild overclock) to play Quake.

Immich has completely replaced Google Photos for me, love it!

My only bugbear is that it is updated very frequently (what a nice problem to have!) which in my case requires a manual once-over of my docker-compose file every time in case there are breaking changes.
