Is it possible to fit the amp board inside the existing box and desolder the conncetor. Solder wires from the main board to the amp, solder wires from the amp board to the connector. For this to work you'd to fit and fix the amp inside the box and bend som of the pins on the connector...

I was thinking on similar lines; if you mount the amp board upside down at the top of the box with the CDC connector mounted as per the design, then you just need a few short leads to bridge the two boards together inside the box and the connector should still go through the same hole. This would save a lot on parts and connectors; further, it might be possible with a small variation to omit the power reg on the amp board and associated components and get 3.3v from one of the header pins (I think some of the earlier versions didn't have diode protection on all headers; 5.0 does).
