I live in a federal school environment, and as a result, we have free-constant electrical supply, which I was expecting to put to good use by mining bitcoin with.

Here's the question(s): Is there a website where I can buy used mining equipment at a low cost? And, if I intend to purchase all of the essential equipment using this technique, what is the estimated cost?


It would also be helpful if you could provide me with a list of the items I will require for mining. Thank you.
