This is just a suggestion for possible improvement on the Ogre design, but do you think you could create an optional enclosure for the gpu that mounts to the dock? It may assist with added rigidity to the setup, allow for the unit to be stored in a backpack/suitcase for travel, and you could potentially add space above the gpu for mounting 2-3 40/60/80mm fans that can be powered using the 12v rail w resistor cables for noise reduction.
