The octanes have awsome processors and internal hardware. Dont think for a second that SGI's hardware sucks. Everything you do on the octane is going to be very fast. But your options of what you do on that octane are also very limited. Your choice depends on what you want that computer to do for you.
Oh, btw, Jaz drives should work with no probs on an SGI (assuming you have the right model, cables, and conenctions). There a very few peripherals out there that are natively supported by IRIX and will work just by plugging it in a restarting; the Jaz drive and the old zip100 are a couple of them.
Stay away from Macs for Maya. Their video cards really suck. And (as a computer specialist in a school) i have found the new line of macs (Dual Precessor G4s, regular G4s, iMac DVs, iMac Special Editions, and a few G3s) to be horrifficly unstable. And we dont even use them for heavy duty graphics or anything fancy. They just plain suck.
Admittedly, NT4 and Maya have their share of conflicts. But with the right hardware, Win2k and Maya3 run beautifullly together. Since I installed Win2k, Maya3, and updated my hardware drivers I haven't crashed out of Maya.
You'll find that the Windows OSes will become unstable and start to crash if you have 10,000 things running in the background...like Instant Messenger, ICQ, Comet Cursor, RealPlayer QuickLaunch, WebShots, Bonzai Buddy, Norton junk...etc. All these cool, free apps that appear in your system tray (next to the time in the task bar) is what makes a windows system unstable, especially when running an intensive applicationn like Maya at the same time. Where I work, all the times Ive had to re-install the OS on a machine was because the user installed several of the above stupid apps and screwed up the registry. If you take care of your system, your system will take care of you.
...oh, MS-DOS...i miss you so...
