i just finished my project, where i put a raspi, a speaker, an amp a DC/DC converter (s and some wireing in a small IKEA Box. The Box has the dimensions of 16cm * 11 cm * 8 cm which make everything little bit complicated. But in the end i could fix all thinks inside... after removing the composite adapter of the Raspi.

The interiour looks little bit messy:
The Configuration of the Raspberry is Rasbian with a Shairport from abrasive.
