Hiya!

I have a Raspberry Pi 4B set up as a print server, so it has to run 24/7. But it irks me that it's mostly idling.

I'd move my website to it, but I don't want to deal with it being open to the internet. The same goes for an e-mail server.

I was also thinking of running a Minecraft server on it. (Being able to play on the same world from different devices is kinda cool.) Alas, my RPi only has 4 GiBs of RAM. I worry that such a load would interfere with the print server.

Any ideas what I could run on it?
