I remember the Cobalt Cube. It was used for one of the first public demonstrations of SELinux released by the NSA. They gave everyone on the internet root that was under a restrictive MLS policy. That little machine handled a large number of people ssh'ing into it none of whom believed they were really logged in as root. I regret never buying one of those little servers.
