This is a 3D model of a frame custom made to precisely fit 20 GPUs, 4 PSUs and 1 CPU. Model can be used as guidance to build your own frame. Drill holes required to mount GPUs are indicated for guidance. Locations and sizes of PSUs, CPUs, and GPUs also indicated for guidance. Suggested materials to use are aluminum channels connected using rivets and wooden slats for the frame's base. Tools required are cutters for wood and aluminum, and rivet staple to assemble the frame. Fun DIY project for those interested in making their own mining rig or GPU farm.
