I set up an Intel NUC mini PC in the following ways:

I installed Arch Linux onto it because I heard it was lightweight, minimal, and difficult to do.

Then I made it so that when I powered it on, it would act as an access point for a network it broadcasts using NetworkManager.

Of course, it also needed to act as a DHCP server, so I configured that using Kea DHCP

Another thing I did was add an authorized key for passwordless ssh-ing

I also wanted to try hosting a Minecraft game server, with a Python script I found to have it automatically show up as a LAN hosted server which normally only is for singleplayer worlds hosted temporarily

And I wanted to mess around with the Damn Vulnerable Web App (https://github.com/digininja/DVWA)
