The Indy was introduced in 1993 as a low-cost high-power UNIX graphics
This is a machine I've lusted after ever since I first saw it, all that MIPS power!
The original Indy was marketed for $5000. I picked mine up for $80 on eBay
a couple of years back. You can find 'em cheaper now.
My Indy is a 200mHz R4400 with a 24bit XL Newport graphics card. I run IRIX 5.3 on it.
The Indy comes stacked with all sorts of ports on the back.
