I like the enclosure it works well.
I have made a few changes to the layout of the box from the work done by Tim. I have removed the USB connector from the Bluetooth module and soldered power leads to a remote USB plug (I was tempted to solder the Blue tooth directly to the 5v input socket, if I ever need another USB socket on the Pi2 I will do this), just waiting for the parts for my mixer circuit there is loads of room around the Pi 2 and PAW.
The end of the box has been replaced with a 3mm mesh to allow the air to circulate.
I have attached an image as to where I have got to.
