hello all just wanted to share my case. It is the perspex cast that my ipod shuffle came in, surprisingly it is made to measure. I mean mm perfect the pi board is snug in there, NOT a mm to spare. you can see in the pics i have not allowed access to the coax and audio ports, two reasons: I have had no call to use them :It would have been messy, my dremmel is off site and i used a stanley/craft knifr to make this. I am however very happy with the results.
tight as a gnats chuff, mm perfect!
