I have 3 laptops I replaced that are a few years old that can still do most things. I have unlimited internet with comcast. I was wondering if anyone had ideas of things I can have those old computers just do running in the background to make a little bit of money? I am not really looking for a lot from them, that is what my main business is for. I just wondered if there was anything I could use them for in automatic mode so I don't have to mess with them?
