I'd also like to find a source for 3 (maybe 4?) of these myself. The SGI
IRIS 1400 I have currently has 240V fans installed, and I'd like to
convert it back to 120V operation.

It appears the system was modified to run on 240V after it was shipped to
Europe. The only changes I've noticed have been that the fans were
replaced, some jumpers were resoldered in the power supply, the metal
plate with the IEC power connector appears to have been changed out, and I
think the power switch was also replaced. The metal plate with the power
connector has the 240V power requirement painted on it, so I know that was
replaced. It appears the original 120V plate may have also had accessory
outlets (can anyone prove or disprove this?), as there are some extra
wires behind it terminated with quick connect terminals. The original
power switch appears to have been a lighted 120V rocker, which was
replaced with an unlighted rocker. The current power switch is already a
candidate for replacement, as it is in pretty poor shape, and has
obviously arced a great deal in the past.
