I'll start. Did you know you can run a headless version of JD2 on a raspberry pi? It's not the greatest thing in the world, but sometimes its nice to throw a bunch of links in there and go to sleep.
Personally I switched away from a seedbox to a VPN, but only after building up a stupid ratio on several trackers. It's annoying to manage two copies of everything, you have to download everything twice, and drive space on seedboxes is expensive.
