This is not the 2560p it doesn't match the images at all.
The 2560p was a 12" model with a black plastic under belly, the location and type of ports also matches the 8460p and not the 2560p.
But overall it doesn't matter they are selling 100-200$ refurbished parts for 100% or higher markup with no OSX installed, so overall it's a pretty scam ;)
