This guy has taken an MSI Wind, and carefully cut the apple logo into the case :) then installed OS X and Lo! Introducing the Macbook Mini :) (As he calls it)

really cool idea, and nicely done, this is what he believes is a missed opportunity for apple, they are still not selling a cheap portable apple.

He presents it here as a parody of the Air advert :)
He is how he did it -
