How does it differ from a regular xbox 360 or the 360 slim?
Here's the difference. It's just a slim design.

Hope that helps. xxox
Phat is Fat = Original
Slim is Skinny = Newish
Xbox 360: Released in 2005 and has Red Ring of Death Problems
Xbox 360 S: Released 2010 and fixed the Red Ring of Death by adding Fans and is smaller.
Ohhh so Phat is the original?
