Idea - Create a space heating solution based on an Antminer S9 which is completely or near silent. - Reuse existing parts of a stock S9 - Use parts that are easily and widely available or are 3D printed - Simple and low complex solution. Goal for anybody to build this at home - Completely Open Source Find all the 3D print files at https://github.com/NakamotoHeating/BitcoinSpaceHeater
