How long does the internal scsi cable have to be for the duodock? Also are there pics anywhere that show how to fold correctly in place? I want to eventually install an HD in the duodock. What is the maximum size of the HD and what else besides the HD, cable and power cable (which is special) do I need? If I want to purchase the whole thing besides the drive where should I go? Maybe someone has a good site they can share. Alex
