Today I managed to solder together the (AFAIK) first PoElli mechanical 
prototype; see the attached pictures. 

A few lessons learned:
- the 11 mm high female header height is good
  - the PCB would rest nicely on the top of the video connector if it was 
soldered snuggly
- this form factor does not work mechanically, it bents too easily
  - no support on the edge opposite to the 100 mil header
- we have to extend the PCB over the RasPi's own RJ-45 connector
  - must have insulation on the bottom of the PCB at that place
- if we extend the PCB all the way to the "right" side of RasPi, we have to cut 
a hole for the dual-USB connector
