gpu mining rig frame rear support not supporting

Once I moved the rear cross rail back behind the 2 rear legs, I now had too much space between the front and rear rail in my mining rig frame, so the rear of the GPUs were floating unsupported. Since these are large and heavy double wide mining GPUs, I didn’t want to have all the wait hanging off of the front brackets, so I added an extra wood piece that the mining GPUs can rest on
