Eddy, you already do the simple backplate for the memory on the GTX280, why not simply adapt this to serve as a "bracing" plate for the GPU screws? Surely it would just be a case of making it a single solid plate rather than the "U" shape, putting a pad in the middle and providing screw holes for the GPU mounts. The screws which surround the GPU could then pass through this backplate, offering support for the centre section where the GPU is whilst also cooling the RAM a bit like the current one does. This wouldn't be too difficult or expensive, would it?
