Awesome comment!

About the dashboards, I have been using CasaOS for a while now, it is not a OS, but it decently handles containers and allows you to install a bunch of services in a very user friendly way. Nowadays (as I found out a few days ago) the project seems to be moving in the direction of a fully purposed OS with NAS capabilities plus the containers stuff. Unfortunately the project (under the name ZimaOS) has gone into proprietary software and (for now) a one payment level to unlock full options with a free limited version.

I don’t think I can recommend anymore to go with casaOS due to that (although for now casaOS remains free OSS kinda separate). I have been also looking for alternatives to set up a NAS and so far I am heavily leaning on OMV as it is a full OS with the idea of handling a NAS with all ready, plus it is based in Debian which is a plus for me too. Alternatively I am looking into YunoHost also, but I think it is not exactly what I want, although it looks promising.

Edit: forgot to mention FreedomBox as another option that can work as a NAS OS of sorts that helps with self hosting services too.
