Use the instructions in the docs for making a service file but replace the jellyfin binary with the flatpak binary (with the jellyfin run arguments)

One with Arch that runs gameservers for my friends, and another that runs Proxmox filled with either Arch or Debian in the containers depending on what it is in them.

You can get an intel arc a310 for ~$90 and it has absolutely insane transcode performance, so depending on how large your library is it might even end up cheaper than buying more storage to just live-transcode everything.

Note that for jellyfin (or any software) to reduce the bitrate it will have to transcode the video

an old LGA2011 xeon workstation. It is wild overkill (and not very power efficient) but it isn’t only a seedbox and it has as much PCIe expansion as I could ever want.

qBittorrent and Proton VPN has worked well for me

What arm board :p
Honest question. All the ones I have seen are really awful and I would love to tinker with something that has real pcie (Ampere workstations do not count)

Extremely useful for lemmy discoverability from mastodon

They admittedly seem to have gone up in price since I last looked, but here is a listing for only $40

You can used Samsung 22110 1TB NVME Drives for $25-$35 and they can be an excellent choice despite the used flash

Your OptiPlex will have considerable PCIE expansion though, so you could slot in a second hand dual-port nic if you wanted to (10GbE might be easier to find than 2.5 and they are still relatively inexpensive as second hand hardware)

Not terribly useful for anything less than a lot of players

You can always use your current router as an AP and use an x86 pc with 10gbe or 2.5gb network card(s) as your main router (or even a switch)

Your vault is always encrypted very securly except when in RAM. There is no security concern with uploading it directly to the cloud.

Do you mean the card with the SODIMM next to the CPU? that is a raid card, and it looks like it is responsible for the front drive bays.
