The board that I took the pictures of with the flash on it is a really
small board, about 1/4 of the size of the gumstix board. The flash on
the gumstix board I received was filed down when I got it, but it
wasn't filed down to make it flush with the edge of the board. This
made it so it didn't fit properly in the case.

The serial connectors on my board have a little lip on them, and the
round part of the lip that comes through the case is pushed all the
way towards the edge of the case (i.e. it isn't centered in the hole).
If you look at the inside of the case then you'll see that the hole is
right next to the inside wall of the case. This is why I had to file
it. I suspect that the parts move a little during soldering. I can see
that the two serial connectors are tilted slightly relative to each
other as well. It's hard to capture the exact details with my camera
because it doesn't have a macro mode.

If I get my other camera back, I'll see if I can capture the problem.
It's pretty minor.

Now that everything fits, my case actually pops together nicely and it
actually takes some effort to take it apart.
