I have incorporated into the housing a newer Plextor DVD burner, works so far properly. The only thing I had to get themselves were fine adjustment screws, as a computer hobbyist has one lying around such a thing, who does not have such a thing, but then has a problem. The screws for fastening the whole are with coarse thread.
Otherwise, there is nothing more to add that has not already written here. Would I buy the whole.
