all racked (well, the 1200 sits on top and the speakers are where speakers go)
A lot of high-end home products (like the Technics ST-9030 tuner) were rackmount or had optional rack ears available, Of course, these could always sit freely on the shelves of an ordinary home audio cabinet if you had no rails to screw them to. When buying home gear I would always get the ears whenever possible, and it's no great shakes to create an equipment cabinet with rails, even wooden ones, instead of (or in addition to) shelves, and a nice wood-finished exterior for improved WAF.
