Maybe! In the UK $100/year gets you about a 20-40w constant load*. That's a fairly efficient machine, and then there's the router, modem etc. Granted some of that already exists, and a Raspberry Pi or similar would fit in that budget. * quick maths: $100/365 gives 27 cents a day or approx 1c per hour - at $0.50/kWh you have a 25w constant load and at $0.25/kWh you have 50w.
