Any 12.7 mm optical drive will nominally fit. However, the plastic front panels of different optical drive models are in at slightly different heights and some may not line up with the front panel opening without interference. We recommend:
DVD Burner Hitachi-LG GTB0N or GTC0N
Blu-ray Reader Hitachi-LG CT30F
Blu-ray Burner Panasonic UJ-260 (tray loader) or Panasonic UJ-265 (slot loader)
