Thing is, it depends on the time. Octane/O2 were beautiful machines for the late 90s, PCs were just beige boxes at the time and I wasn't overly taken by the translucent plastic Macs of the time either. Same goes for the Indigo2/Indy (even Macs were beige boxes at this time). I did think the PS2 was also a very cool looking device for its time as well.

Part of the reason the Indigo2 is my favourite SGI machine is that I was raised in a world of beige PCs, then I saw a room full of purple Indigo2s with granite monitors, they looked sublime back them!
