I'm at re:invent and they have a "making of" video next to a demo unit. They only show the physical construction of the power distribution and the raised floor.

I'm at re:invent and they have a "making of" video next to a demo unit. They only show the physical construction of the power distribution and the raised floor. (Nothing about the racks or what's in them.) It also appears that you never have access to the inside where the racks are. You can only access the last ~4 feet for power and data connections.
