What should this Z1500 be? It most likely needs to be full width like a UHD2000 but single bay like a Z1000. This bay is 5¼ inch wide and allows for a choice for a PC 5¼ to 3½ Bracket, BD ROM or UHD/BD ROM drive.
It must have a bracket so that a computer drive can be installed there, but it is better if it is already installed. And it’s good that he reads not only videos, but also sound discs.
