"Looking at the thumbnail sized photos on the box, I tried to figure out some of the other configurations of the rack. Some of them appeared to have the rack "arms" mounted perpendicular to the rack. In this particular case, the "arms" were much too long to mount that way, even without a motherboard installed, so I assume that it is not one of the configurations. The only way I can see to mount anything in front of the PCI slots is to mount one "arm" parallel to the rack, and only have screws in one side of the drive, radiator, etc."
