I need some help..... I am just getting around to upgrading my Rev A with a CD burner and I would like to have it internally vs. external. I can't remeber the name of the company that manufactured the CD-R tray that replaced the standard CD rom tray on the Rev A-D's. I would really like to get my hands on one of these, but I can't seem to find any out there. Could someone please tell me where I can get one of them? I am really lost here.
