Hey i am currently selling some rigs that I made for $3,000. They have a rate of 179 MH/s which is very good for this low of a cost. You can also buy all the pieces separately and build it yourself. If you have any questions on how to get this or the details of the rig you can contact me on WhatsApp at 1-919-624-3675. I can also answer any other questions you might have.
