What does the white sticker on my Mac Mini late 2012 logic board mean? C07414302RHF1H8AM    631-2014   CHINA Current repair is telling me that previous repair swapped out my original logic board claiming they resoldered the board fan connector because there’s no connector repair. Is there any way to tell that from the letters/numbers on the sticker? What do the letters/numbers indicate? My original board was a 2.3 i7. Is there any what to confirm that from the sticker on the board or prove that it’s not my original board?

The first part is your systems serial number C07414302RHF1H8 should match the cases S/N stamped on the bottom if its the original board. The last part of the S/N F1H8 is the logic boards configuration in this case a 2.3GHz i7 CPU is mounted to it. The 631-2014 is the logic boards assembly ID (not used) Here’s another board as reference:

FYI: The Apple part number is 661-7018
