We are excited to announce the QuadAxe insert for the Antminer S9 chassis. The QuadAxe serves the purpose of housing four open-source Bitaxe Bitcoin miners within old, obsolete, recycled Antminer S9 chassis. Our primary focus is on repurposing and recycling Bitcoin e-waste whenever possible. With the QuadAxe, we provide a highly capable housing for four Bitaxes, featuring effective thermal management facilitated by the ability to mount two 120mm fans, along with added protection for your Bitaxes.
