Are you sure about the FZ-357 being a high density drive? I have a couple here, I assumed they where "full height" 880k drives as I also have installed FZ-357A and FB-357A drives which are high density for sure (just one is a taller drive). The FZ-357 drives I have include white bezels and a white eject button instead of the longer tan (and angled) eject button on a non-bezel 3000T drive.
