That sounds more or less to be exactly what I’m doing with NPM currently. I don’t see how it’s easier to configure as all I did was fire up the NPM container, log in, and add my host targets.
NPM also handles SSL both standard http verification as well as DNS auth for wildcards.
Whats wrong with NPM?
Its just a computer, nothing more. You would do exactly the same thing as you would on a desktop or vps.
No you do not have to plug in both power cords but if both aren’t plugged in it may blare an alarm. If so plug in the other or just remove the redundant PSU.
+1 for restic. I have additionally started using autorestic with it and have been happy how it operates.
Set up what you want on what you already have and if your workload is more than your hardware can handle then upgrade.
Overall most of what you rattled off isn’t too resource heavy but 12gb of memory isnt exactly a lot and i dont know what your minecraft server will eat up.
Alternatively look up the recommended minimum specs for each of your desired applications and add up the needs.
Additionally if this isnt going to be a headless system and you want a desktop gui that consumes resources as well.
