Jackett can be run on any computer. It doesn’t need a server or any serious hardware. It can probably be run on a $20 Pi. It’s just allows you to interact with trackers via API calls.

I use Prowlarr via Docker now a days. It’s provides a much better experience to interact with othe instances of ARRs.

I would just keep my PC on 24/7. Did that for a good decade before I built a server. Now the ARR stacks make torrenting on private sites effortless.

Running qBittorrent over web UI was a game changer. I was running it off a personal PC for the longest time (usually my newest gaming machine) but finally built a dedicated server.

Whose ready for some AOL ultimate Frisbee?

To answer the question, I don’t think they should be used for anything. Keep a small stack for a rainy day and get rid of the rest. There is a reason they are all it thrift stores and being given away for free. Their are much better alternatives out their for storage. Unless you are a hoarder. Then, just add them to your pile of crap you will never use/need again.

I have burned thousands of CD/DVDs in my life but maybe only 10 in the past 15 years or so.
