Cooling two air cooled graphics cards with no space between them is not ideal, so you may want to consider adding space between them or a water fill port and reservoir mount for custom loops that could handle them.I have an old prototype laying around with a similar layout, made from a 2mm steel body and a 3mm steel back panel. It's not in use, but that 3mm steel panel makes a great mousepad.
