I am running a set of SBCs, but I read that it is better to use one server [1]. I suppose one could go with a VM, or portainer, or Yacht, or some other software to visualize everything.
Right now I am using a set or solutions:
* email * [2]
* files * using NextCloud
* blog * using Hugo
* news * using my own RSS reader
* pihole * to filter things
What I consider to use in the future
* pictures * using photoprism
* citadel * I found some sort of suites like citadel. Not sure if that works, if it is good, or if it fits my needs at all [3]. At the first glance seems like a fun project.

All in all it is time consuming to setup up, and update regularly.
