Just be careful on older non-autosensing power supplies where you have to flip a switch to go from 100-120V to 200-240V input, in that you make sure to flip them to begin with, and that you flip them back should you ever mover them back to a 120V circuit.
Been there, done that with my nagios box when I had to replace a fan years ago. The build table was 120V so I flipped the switch and forgot to flip it back. It actually booted for about 5 seconds before things inside the PSU started exploding and spewing magic smoke. Scared the daylights out of me. No damage other than requiring a new PSU. ~Seth
