One place I worked had the storage array cabinet from a Connection Machine, which was outdated by that time, sitting in a lobby area.

They sometimes used the cabinet as a bar counter at VIP events (with uniformed catering service bartender behind it, in the curve). I assume most people didn't know they were getting handed their glass of wine over a piece of history. I only knew because I recognized it and took a closer look.
