<I know why. The heat dissipation system won't fit in a Cube. Hopefully <Sonnet and PowerLogix are also working on this for us. Or maybe OWC is <working on an alternative design that will fit later. We can always <dream. This shouldn't be a problem - pry it off and put it in a Cube with a base fan - should work, since the Cubes heatsink is big enough!! Boris
