FriendlyElec Nanopi R3S

Would be a nice DNS & DHCP server

My current home "NAS" still uses USB2 so this would be a great upgrade.  I think I'd also like to run a private runner for Github Actions that require an ARM host.

I would like to learn more about electronics and circuits with this device.

I am a fan of such mini PCs and I would probably have a lot of fun and testing e.g.:
ftp server / libreelec / coreelec player / internet radio based on mpd mpc / Jellyfin / tvheadend (dvbt2) etc 🙂

Not participating (tax reasons), but you could run Ai network attacked with frigate.
