Hmm well I like it but look @ the second pic:
You'll notice two things immediately. In this picture, the optical drive eject button has an arrow pointing up, whereas in the previous picture, it points left. Also, in this last picture, "memory" is all lower case, but the M is capitalized in the top shot. Also, on the left where the hard drive is attached, there is a notch, or perhaps an LED indicator for drive activity or status. This is missing in the top image, as well.
With that I think its a fake or very ealry mock-up
