A simple question to this community, what are you self-hosting? It’s probably fun to hear from each-other what services we are running.
Please mention at least the service (e.g. e-mail) and the software (e.g. postfix). Extra bonus points for also mentioning the OS and/or hardware (e.g. Linux Distribution, raspberry pi, etc) you are running on.
I run k3s on a similar setup, 4x rpi4 and 2x Intel Atom mini PCs. Obviously different software with different goals, but was remarkably simple despite the heterogenous platform.
