Intel N100 Beelink box with 16GB of single channel RAM runs my Jellyfin server and Caddy. It's also hooked up to my home theater system directly so I can use Moonlight on it to stream my main gaming PC.
My storage is a 4-bay aluminum USB 3.0 external enclosure attached to an M1 Mac Mini running Asahi Linux (Arch BTW). The Mac mini runs my Arr stack and mergerfs on the external drives so I can load balance across them and scale it up or down as needed. So basically the Mac Mini acts as a NAS.
