Nice score! I have a B&W and Quicksilver that I wouldn't mind sticking ZIP drives into, but only if I can get the appropriate bezels (I'm super picky like that!). The bezels, it seems, are difficult to come by unless you buy a Power Mac with a ZIP drive already installed.

Right now I'm getting by with my SCSI ZIP drive attached to my B&W (alongside my SyQuest EZ135 drive) and the ZIP module on my Wallstreet II.
