The lid and sides of the case have pin holders so that you may put all the connected pins into them, the idea is to never have to connect and disconnect pins on the arduino. All the pins will be connected at all times and you will easily be able to connect and disconnect new connectiions from the pin holders. Obviously you'll have to either color code or remember the pin# of each. The case is specifically made to have screw fittings for specific dimensions, if you contact me i can alter the distance to fit your purpose.
