There's a screencap of me out there saying something like "Don't casemod any SGI, unless it's a Fuel" - which is a riff on that every SGI except the Fuel uses a nonstandard board size and case. But even now, I would probably just shut up if I saw a Fuel being ripped apart and ATX guts shoved inside.
The reason being is that these systems are expensive, and destroying a specific case or part just to turn it into art or a generic PC case or whatever would simply ruin something that could have been used. That being said, there's people out there who painted Octane cases red, O2 cases white, Onyx2s purple and white etc.
Personally, if I were to do something like that, I would want to rig up a set of adapter brackets, and make all mods reversible hence off that, rather than cutting up the case. That would probably placate those of us who would freak out.
Here, I'll explain what I mean by the above:
Go to a hardware store, buy something called a "rubber expansion nut", it looks like this:

You can glue those to the bottom of the case with some kind of epoxy and if you get a good size you'll be able to create a mounting bracket that you can put boards of any kind on, and then you could fabricate a steel plate to cover the unused holes on the Indy and fasten them in with port anchor nuts (like those nuts used for serial ports or VGA ports etc.) and then from that you could jerry-rig something.
Now, as Kaigan points out, this is just an opinion. It's not our business to demand what you do with your hardware, but I will frown upon it even if you did turn it into an otherwise kickass machine. Simply put, it feels wrong to me. You can share it here, but like anywhere else people are free to praise or criticize it. If they insult you personally we'll remove it, though. Going to the effect of "hurr hurr retard modded an old SGI what a moron." type comments are immature, and I realize they don't offer anything to adult discussions. So we won't allow people to be assholes.
Moreover, I have reservations about whether the Indy makes sense. As for MaXX, people here know my opinions on the guy - I don't like his software, his attitude, or his past in the community. Broken promises and all that. It's hard to replicate IRIX on anything but IRIX, but E16 has the IREX theme that comes close!
Little tangent, but if someone has access to CNC machines or a large enough 3D printer I'd be down to help setup an irixnet kickstarter where we could do a run of ATX-style cases based off the Indy or o2 or something. That'd be the shit, and I think such an opportunity could be done in multiple styles and dimensions.
