I recently had the same problem. I purchased an SATA DVD drive for my replacement. It was about USD $30. I had to get two cables, a power adapter for the SATA power plug and also a SATA cable. On my Mac Pro, the SATA cables with a right angle connector on one end work best. There are tutorials on the net for the take apart of the computer.
