While it is a beautiful looking Indy, I can't help be sad by what's happening to these prices. The impossibility to get cheap, admittedly useless SGIs like the Indy means the hobby basically dies with us. I first got into tinkering with SGIs over 15 years ago. If the entry-level super slow SGI (which let's be honest, is what an Indy is) was in the hundreds of dollars range back then, I never would have afforded to get into it.
And I mean no disrespect to the seller here - it is a pristine looking example, and pristine examples will always carry a premium (and rightfully so!). But it kills me that even the cheapest Indys on Ebay right now would cost over $300, take almost 2 months to get here, and isn't even tested. We're killing the future of our own hobby by pricing people out of it for machines that while cool, are less useful than a $35 Raspberry Pi...
