Raspberry Pi Lego Cases — kevinbecker.org

Here are a few random links with information about Raspberry Pi cases.

Rpi Cases Wiki Page - as of now it has two lego case designs, including the Lego Digital Designer file for one of them.
Raw measurements from one of the beta boards
Two different Google Sketchup models based on the above measurements
Perspective corrected images of a beta board

Using the lego case model above as a starting point, along with the measurements from the other links, I'm going to try to work up my own Lego case.
