For any of you fellow Navigator owners out there, I have always left an open space beneath my Navigator, because I didn't want to take off the rubber feet, and becuase it has one or two large honking screw heads on the bottom, and it looks like they will gouge the top of whatever goes directly underneath the Navigator. But, I'd really like to cut back to a 6 space rack, and to do so, I would not be able to leave any open spaces with my current configuration (PL-Plus, MDB-1 and ULXS14, Navigator, and PLX 3002). Have you guys had much luck putting something directly underneath of your Navigator? Did the screws scratch the gear underneath? Did you take the rubber feet off? If so, how did that go? Any advice (and shots of racks with Navigators in them!) would be appreciated. Thanks, Tom.
