I can't remember, what color is the case? It is a silver gray right? That unit is very similar to the 520 series so you could look for a drive from one of those units. Of course the drive uses a standard sized bezel so you can put any drive you wish in there, though the color may not match. The 520 series uses a M/S (master/slave) drive, so make sure you get one of those instead of a CSEL (cable select) drive although I know of a workaround that involves soldering. One other thing you can do is purchase a drive that is the same brand as your current drive and then take the bezel off your current drive and put it on the new drive so that the color matches up perfectly.
