Hi, Today I was in the Apple Store and found out my MacBook has no serial number. I bought it recently for 100 euro's and installed an SSD (vertex 3) and an new black topcase. I wanted to go for a black bezel at the Apple Store. That makes it a black (on the inside) white macbook. Pretty awesome looking. Little fun project. Anyway, see the picture for what I mean. They did not know either.
