Based on your ebay link, the cheapest PCs are around $50 shipped. Including the electricity, that's $70/year. So you'd need more than a year to have this approach pay off, and additionally you will have saddled yourself with managing a physical machine rather than have someone else abstract it for you.

Doesn't seem to pass the "it'll pay for itself in a couple months" claim.

That link sets the max price to $30. (I see a few at $18) I'm not sure how you found a $50 item there. Ignore shipping if you're adding that in, there's lots of local ones you can find on Facebook market and similar sites.
