We had a few ex-mining company workstations at the computer club at university – I remember that the metal security bar through the Indigo workstation could be pulled out and waved at one's fellow users, usually in good fun. :)

They were fun machines to play around on; even when we first got them c ~ 1999 PCs with a graphics card were catching up, but there was just something solid about them. I miss those days of *NIX workstations.
