Essentially its a paid seed box. It has most things already cached, and if it doesn't, you can copy in a magnetic link and it'll torrent it for you and save it to your account cloud (and presumably make it available for other users but it counts against your credits so delete it when you've watched it).

Personally, I've rarely had to get it to pull a feed for me, it has nearly everything I've wanted cached already.

Things just seemed......simpler back then.

Ahh yeah. Good ol winaock. DLL. Just copy the DLL and magically these programs are connected???

I went off the power supply maximum output. 5.1 volts, 3 amps, so 15 watts per hour. 24hrs per day, 365 days a year, so 131,400 watt-hours, or 131kilowatt-hours. My electricity is about $0.25/kwh (advertised at 0.09/kwh, but when you add on bullshit fees, the final rate is much higher), so I came up with $32.85 as the maximum amount any device connected to that power supply could cost.

A realistic Pi 4B-only estimate is about A$8–A$12 per year in electricity

That's about what I calculated for my locale. Roughly $0.30–$0.85 per month, around $0.48/month at 4 W. Which is remarkable especially given what you can run on one.

¯\_(ツ)_/¯ i'm on two private trackers that aren't that hard to get into and I routinely download 10 plus year old 50 - 100 gb files with good seeds. I have never run into something not decently seeded since I went private.
