Honestly, unless you can spend more $, one or two USB disks for the mini pc is probably your only choice.
From your description I would gues that the affected trackers have some rate or connection limits, and your qbittorrent announces are exceeding them. try setting a higher announce interval, like 1+ hours
I'm surprised no one mentioned ansible yet. It's meant for this (and more).
By ssh keys I assume you're talking about authorized_keys, not private keys. I agree with other posters that private keys should not be synced, just generate new ones and add them to the relevant servers authorized_keys with ansible.
no, its personal preference
I'm using organizr, it embeds your apps in tabs/iframes and allows you to configure them in the UI.
same here, lol
I don't think you can force anything in this regard. There is the official forum, reddit and here. People will just naturally ask wherever they are comfortable.
750gb upload, 5tb download per day. However this seems to be another limit, maybe file based max sharing or something.
guys are not downloading enough ๐

It matters only if "the docker hosts external IP" your dns resolves is a public IP. In that case packets travel to the router which needs to map/send them back to the docker hosts LAN IP (NAT-Reflection). With cgnat this would need to be enabled on the carrier side, where you set up the port forwarding. If that's not possible, split-DNS may be an alternative.
If "the docker hosts external IP" is actually your docker hosts LAN IP, all of that is irrelevant. Split-DNS would accomplish that.
It depends on your usage. If you are downloading hundreds of GB per month or more, a block account does not make sense.
Personally I get almost everything off torrents, so I also have some Block accounts which last me many years for the occassional use.
If this fits your budget (you still need the actuals disks..) it's not a bad choice. Speed should be sufficient for HDDs, as it's USB 3.
As the other poster suggested, don't use its hardware raid. Use it as a JBOD and configure the raid in Linux with ZFS or similar.
And never forget: RAID is not a backup! You still need to do regular backups, at least for important data.
