I once had a cage that was all 220v. Wasn't an issue at all. Had two
devices that required some effort to work around...

1.	A small media converter. This was powered by a wall-wart style
	power supply that fed it 12v DC, but, the wall wart that shipped
	with it did not handle 220v. No regret, but, a quick trip to Fry's
	to buy a suitable universal wall-wart with 220v capability and
	problem solved.

2.	Our cordless screwdriver charger would not accept 220v.
	Initially, we just plugged it into an outlet in the customer work
	area whenever we were at the datacenter. Long term solution,
	we bought one of those international transformers and
	hooked it up that way.

I think we might have built some of our own adapter cables to
deal with plug issues, but, it's pretty easy to build 3-wire pigtail
converters and Home Despot has all the necessary supplies.
