interesting, however, an enclosure might trap heat dissipating by fins, so maybe enclosure around PCB with fins protruding out?
then, it would look similar to some graphic cards.
heck, maybe, once he switches to BF chips, one can envision a "hanging" design similar to what people do with GPUs on metal racks.
then, a big fan could take care of a multitude.
I am working on something now for stacking two or four Superbpag hubs side by side and mounting a 80mm or 120mm case fan on top of them (the image below is for the four hub version). I was sort envisioning something similar for the pods (although oriented differently to account for the second heat sink). The idea being by forcing the air to flow across the heat sinks instead of just flowing in the general direction of the heat sinks we can get better cooling.

The body shown in the image is looking from the top through to the bottom. The body will sit on top of the hubs with each of the 2Pac's in their respective walled off area. The bottom is open and there will be a fan on top so air will be pulled from the bottom to the top. There will be an unpictured body that goes on the bottom that will support each of the USB hubs and keep them in place and provide support for the pictured body. I am still early in the design phase so it may be hard to envision.
