Jassper:
Those are both great documents; a link to this thread, and links to those documents should be placed in the playground, probably here under a new section called "Enclosures":
http://www.arduino.cc/playground/Main/ElectroInfoResources
CSingleton:
Your comments on low-cost/low-run prototype production techniques should also be placed in the same section.
I think all of this needs to be documented there.
Bravo!
