Hey folks, When I got my Mac Pro I immediately connected a Sony burner I already owned into the 2nd optical drive bay, removed the plastic front face piece of the tray as mentioned in previous threads, only to find out that the tray still clips the drive door so it gets stuck. (argh!! If only Apple gave a few additional millimeters!) This is a case where that extra few millimeters in tray position meant the drive was physically incompatible with the Mac Pro. Before I go shopping for a new drive, I'd like to find out if you guys have recommended brand/models that you KNOW fits into your Mac Pros (because you installed it and it works, duh). I tried "eyeballing" tray height in online pictures, but they all look about the same. And you never know until you take off the front face... Thanks all!
