Debian only household here …

With the price of a lot of the SBC’s you will probably be better of going for something like as dell 3050 with a gen7 or above in it. I picked up a gen7 dell 3050 with 4Gb and a 500Gb disk for £50. Threw in a 1tb nvme a 120gb ssd and a spare 500GB ssd I had. Installed Debian with KDE , then i set up the drive shares via sftp, installed Docker and setup the various docker containers such as freshrss, kodi, Firefox ,Pi-Hole etc.

What ever route you go have fun starting you journey in the world of self hosting.

Cheers, always nice to find something new to play with.
