I installed a bluray drive in my second optical bay. The only difficult part was running the SATA cabling from the extra ports on the mobo to the optical compartment. Mine is the 1,1 MacPro though. I don't know if any of the newer MacPros have SATA going to the optical bays already. You could just lay an SSD in there and it wouldn't harm anything as long as you don't move the machine around much. Or you can get an adapter to make it fit into the optical "holder".
