Macbooks from the US are identical. I've got one. It was from a batch of US laptops that were redeployed to Europe for sale to meet European demand. I bought it through the Irish Apple store. I know it came from US stocks because Apple support noted it when looking up the serial number. I got support on it after they realised it was shipped from China to the US originally, it wasn't in their normal database of serial numbers.
The support people didn't care where I bought it.
