to the increasing standards for cable management compatibility in
computer cases, the rails are actually designed for the HDD connectors
to be facing the rear (right side panel) so the cables will remain
hidden for a cleaner look. If you refer to the pictures below, you can
see how the drive rails are meant to be attached for the drive to mount
properly. The GX-500 and P70 enclosures use the same HDD rails.
