I started this homelab around 2018 and have been adding to it since then.  I am now able to support around 10-15 users and provide with some personal space, a chat server, a nice online library and various other smaller services. I'm always looking for more ideas on what can be offered by my homelab.
This project costs kWh and I'm more than happy to support it on my own... BUT I hope you are more than "more than happy" to support also!

Cheers!
