I have an Acer Nitro 5 gaming laptop that is currently not being used. Would that be good? Overkill? Under powered?

I use Debian for my main distro for my personal laptop. Would that be good? Should I have stable or a rolling release?

Is there anything special that I need to do on my home network setup? Create a DMZ perhaps?

This is my first self hosted project, so any information or advice is appreciated.
