The Background: I currently own the LE Halo box. Crystal box is currently in transit from Germany...
The Obvious: 240v PSU in the Crystal box, 120v US voltage. I've seen the aftermarket dual voltage from Lin Sang (among others) which is the best choice IMHO.
The Point: Has anyone mapped an Xbox PSU board or done a voltage conversion on the board itself? Shouldn't be rocket science.
Thanks for bringing this out in the open. I've had a very rough 2 weeks searching for the answer and my philosophy is: If you can't find the answer, you're asking the wrong question. That applies for Googling too.
