So this is the prototype a friend has made that holds 8 GPUs, which will work well with the 16x 8 way splitter that is currently under development. This is NOT a final design and there are already a few things I want changed, but it's progress in the right direction. Welded aluminum frame and we're shooting for a selling price of $100 worth of GPUC.
