The firm misspelt "Evangenlion" on it, adding an extra "n" on the I/O heatsink.
It was a $700 motherboard, and you should expect perfection, but still, it is something that only some would see or spot.
ASUS has officially stated that users who find the typo on their motherboards unacceptable can contact ASUS support for guidance on the replacement process.
There is no indication of a dedicated service to handle these replacements on behalf of users. So, users will be asked to disassemble their motherboards themselves.
