Looking at getting a miner to play about with at home. I know it isn't going to be profitable, I am doing it more for the education. I looking for a second hand S19. I want to go full miner rather than something like a bitaxe or appolo for a couple of reasons. 1 I have excess solar I want to use rather than giving back to the energy company for nothing. 2 I would love to look into using the heat. Thoughts? Suggestions? I am currently looking at a second hand S19kpro for $700
