Sure, I'd love to do that, actually I'd like to make some YouTube videos about them, starting with the Indigo. Retro SGI machines are an absolute addiction because they had this mythical status back in the 90's - they cost tens of thousands of dollars, so only studios could afford them, and for a while they were the most powerful graphics workstations in the world (as well as the most colorful). If you're interested, there's a great web site for SGI enthusiasts called Nekochan.net.
My addiction started with an Indigo2 (the tall purple tower on the desk) and expanded to two Indys, an Octane, an Indigo, an O2, and a deskside Onyx and Crimson (the Onyx is the large black system under the desk with the purple stripe). When new in 1996, that Onyx was a $500,000 system. I bought it for $500 from a very nice fellow in San Francisco back in 2005. I've also got most of the high-end graphics suites that were available for SGI back in the day, 3D animation packages like Softimage and PowerAnimator that typically cost $15,000 or more. If you keep your eyes peeled, you can find this stuff on eBay every now and then for cheap.
Someday I'd love to do something "useful" with them, like create a networked renderfarm and use it to produce 3D animation.
