I would be brutally disappointed if this had an open back; a set at that alleged price should either come with a boatload of figs in my opinion, or be a gorgeous display piece. I would love a dollhouse opening like the GBHQ but I'm absolutely biased as a build-to-display AFOL. Heck, even as a kid I hated that all of my favorite old HP sets had open backs and sides that made it very hard for me to set them up and enjoy the view.
