I'm not knowledgable on theses things.... but has the revision been turned around 90 degrees?
Because I see on the original in the top right of the photo are what look like the ports that the PS3 has under the flap thing... which means that is the front of the PS3 and thus the motherboard is shaped to fit the PS3 shape (wider that it is deep)
On the 2nd picture those ports are on the left hand side, but that is still of course the front of the console....which means that the board is actually deeper (front to back of PS3) than it is wide.... and there must then be some space cleared especially along the edge that the power button is.
