Aluminum or Metal Ultrabay Slim case

[xaveon]

Does anyone know if there is a case for the UltraBay Slim? I am primarily using the UltraBay Slim with a 2nd hard drive, but I would like to carry the optical drive with me. I'm affraid that it won't be very safe for the optical drive to stay in my backpack without somekind of case. Does Lenovo or any other 3rd party manufacturer make a metal case for the UltraBay Slim (to house it while it's not in the laptop)? I've searched around but no luck so far. Thanks!
