I did the same thing in college, in 2003 or so! I had a whole polyglot UNIX lab in my college dorm room; pizzaboxes, SGI Indigo 2's and an Indy, a NEXTStation, random PPC Apples, an Atari Mega ST 2... I remember my RA checked it out and he just looked at it and nodded. No clue what anything was, just "yeah, technically this isn't breaking any rules..."
