Do tell me if you find someone else.. I'm in the market for one, but don't need the drive bay and don't want to pay $90 for it. I've spent about an hour looking for one.

The connector on the optical drive appears to be a JAE KX14-50K2DE .. so basically you need a cable/board to go from JAE KX14-50K2DE to 2mm pitch 50 way pin header (or alternatively, a 44 pin 2.5mm pitch header for full sized IDE)
