It was a C= 128D in new condition with original box.
When it arrived the unit itself looked mint, with all manuals sealed in plastic and all cables still factory wrapped. But the serial number on the box did not match the serial number on the unit.
Now I think I might send it back, because I collect new items in original boxes. So I mostly received a very nice computer but I feel bad about it because the serial numbers dont match.

What would you guys do? Keep it because its so nice or return it because of the box? I paid $250 USD for it, and another $50 for shipping.
