In the past it's been about heat dissipation/heat sinks. The 450 SM
boards get a little warm. Maybe the 450i SoC is better suited to the
Force180/200 style enclosures for this reason.

First one will look a lot like the Force 180. List is $299. Full
band, full speed.
Second one will look like the Force 200 (scheduled for October).
List is $349 IIRC.
