PlanetCrypto, thank you so very much for the detailed answer. It is as I suspected, and I appreciate your thoughts. Nice set up, if you come across any pictures, I'd love to see one installation. I'll check out the links later.

You're right, I would MUCH prefer a C1 instead of the S3+, but I don't think it makes any sense to chase down a cheap one now and throw MORE money into BTC mining. If one came my way, fine, but I don't want to chase for it.

That said, I'm enjoying this little project, and would consider buying whatever comes from the mind of sidehack and Novak to upgrade the S3+. Sidehack and I don't agree on economics and what constitutes profit, but I like how he works and want to support the effort.
