May depend what you want and where (location can matter a little bit for latency critical stuff, but streaming video won’t care), and what operating system you would run on it. The Hetzner ARM servers are pretty cheap for what you get (and it looks like they include 20TB of bandwidth). I’ve been pretty happy with Lunanode. I think people often look here for deals: lowendbox.com they often recommend Racknerd boxes… I think there’s some affiliation with Racknerd and lowendbox.com, but I threw something on a Racknerd machine recently and have had a good experience so far. You may want to do some research if you want to send mail directly from these machines. Not everybody allows it (sometimes you just have to ask), and I hear tell that sometimes you can end up with an IP somebody spammed with before with a bad reputation.
