Maybe it's just me but I'm digging the front I/O. @dondan speaking of I/O, have you thought of having combo mic/audio instead of individual separate mic and audio - I'd thought that would make the I/O look a little cleaner.
I'm digging the V2 option B. Why I voted for option B? Well, it's because it remind me of the V1 case - simplicity and straight forward case, nothing too complex.
