I cobbled together a bunch of second hand stuff from eBay. An i5-12500T is at the heart of it for hardware accelerated encoding, 32 GB ram, an HBA controller for the 4 SAS drives (2x 11 TB and 2x 8 TB). Stuffed all that into an old atx case with an old PSU. Added a tiny touchscreen display for troubleshooting.
I'm pretty happy with this setup. I'm using Unraid and I'm running an arr stack, downloads are done via usenet. Also running jellyfin, Navidrome, Komga, Immich and Adguard.
Im still looking for a good Filesharing service that's easy to configure and allows user registration.
I'm fairly new to all this. So it's an exciting journey!
A Xeon E5-2650v4 on a Supermicro X10DRL-i and like a million dollars worth (128GB) of DDR4.
I wanted something I didn't have to worry about. Beelink mini PC with an N150 and 16GB RAM.
N100. Cheap enough (last year) and plenty of power to run things like jellyfin on it as well. linuxserver makes great docker images.
I have a HP microserver running Debian and Docker. But it runs far more than just HA. It runs all my self hosted stuff except for my pihole.
A supermicro 5018A-FNT4 with 16GB RAM. HA takes up about 25%, the rest is influxdb and Grafana.
