I’m constantly building in the space. I give to you my latest. The hash box temp controller. A heater control for your miners. Ready for pre order ship In about a week. Why turn em on or off? Why open n close windows. Now you can just regulate the hashrate to maintain your desired room temperature. Works on 3 rigs per unit. 200$ pre order price. 250$ after pre orders are over. Can purchase direct from me or through Cryptocloaks. Gfy
