Dell optiplex desktop or workstation would def be a gpod idea. Both are much quieter than servers - you can get the workstation if you want a xeon chip and ecc memory - otherwise the desktop will likely do what you need.

Oops!

Look into PICO PSU. Its a small powersupply that uses a power brick to downsize internals. It’s used by homelabbers sometimes.

If Tidal isn’t your cup of tea, check out Qobuz - I’ve had a better experience with it. It doesn’t pay artists as well as spotify, but I think it’s still more than Spotify (iirc)

Handbrake is a frontend to ffmpeg, so that’s also an option

Perhaps you could configure more than unbound service behind a loadbalancer. Each unbound instance is configured to use different upstream dns servers.

Double check if unbound doesn’t allow you to randomly hop between dns upstreams first, but the above solution should work if that’s unavailable atm.

Also introduces the possibility of DNS poisoning

Yes its possible 👍

Use:

forward-zone:
  forward-addr: 9.9.9.9@853#dns.quad9.net

UNRAID is designed to run off a USB drive, they have recommendations on what USBs to buy on their site, might be worth a gander. You should be able to write all the info on your current USB to the new one without having to reconfigure anything.

If you virtualize unraid, unraid wont have direct drive access - you can get around this by getting an HBA card and forwarding that to the unraid VM. Others have mentioned that proxmox doesn’t have docker support, I personally run docker containers within lxc boxes on proxmox. There are solutions to make managing containers easier, like portainer, if you want to go down that route.

Virustotal can scan APKs afaik

There was an antivirus that was caught running a bitcoin miner in the background tbf. If memory serves it was Norton?
