Vertical Mounting?

Hey all, as I look to set up my mining farm…Setting up my machines vertically makes more sense to me, than the more traditional horizontal method. My question is how do those of you who mount your machines vertically do it? Do you just set them upright on a mesh shelf? I was actually hoping to mount mine to the wall of my garage, spread out around the garage to help spread out the airflow/heat throughout the building. Do you just hang them by the fan mounting screws? Is there some sort of bracket made to hold machines this way? TIA
