I see that the clear shell has a cut out in the back where the cables could supposedly be run if you were to stack a Cube on top of another, and that the cage is wider at the bottom than the top, to allow stacking.
But how would you use the DVD-ROM drive on the bottom machine? Would the bottom machine be able to stay cool even though it couldn't let hot air out of its top? If you stacked a few of these things, wouldn't it get a bit tipsy?
Anyone know for sure if the Cube is officially stackable or not?
