O2 ODAC Headphone Amp Case

I created this case to hold the famous ODAC external DAC board and DIY O2 headphone amp, designed by nwavguy.

The two unique features to my design are 1) Wall power socket relocated to rear and 2) ODAC placed on bottom of O2, retaining the two 9V battery slots.

EDIT: New version (v2) has improved fit and supports standard power jack
