Exactly. Post it to a Programming forum because… you know, computers and stuff.

The most important thing is to buy whole beans and grind them right before use. All of the flavor compounds will be fresh.

You need to supply your own ROM of the correct version.

I went with Debian and I use Docker for containers. I considered Proxmox, but I didn’t end up trying it. PiHole is a good application for the Pi Zero (I have an early generation Pi dedicated to running PiHole), but you could also run it on the Beelink.

I strongly recommend you download Obsidian and keep hyperlinked notes on everything you do and links to every tutorial/resource you end up using.
Have a place to keep all the passwords your services will end up needing. A password manager is the best option. Make the password on your admin account on Debian (or whatever) easy to remember and enter, since you’ll need to sudo a lot.
If the Beelink comes with a copy of Windows installed, you can recover the key from within Linux with the following command:
sudo strings /sys/firmware/acpi/tables/MSDM
Then you have a spare Windows key should you ever need one.
