The software part is easy. One is called Xaudio WinCE and the other is called Utopiasoft Hum.
Storage is fairly easy to overcome.
The bigest problem is output. The only sound output is the little peizo speaker that you can barely hear unless you are in a really quiet place. Once the top is off you can see the backside of the peizo speaker and it's connections. You will have to have a hole in the upper and lower halves of the display casing because the height of even the subminiature connector is as about the same as the external dimension of the case. I have the jack port on the topside of the case.
