Curious about that one myself ... I thought all Macs of that era had different analogue boards for US and International. I think the international version is the only one with a convertible 120/240 power supply via the jumper Stuart references. I'm not sure why he runs it at 110v, except that the power transformer and related parts (caps, resistors and rectifiers) don't have to work as hard to step down the higher voltage (though they are certainly rated for it), so for those parts I guess it would extend the life and durability with a net effect of creating less heat inside the case too (less energy to dissipate), thereby reducing the stress on all the other components.
