Thank you for joining the Intel communities.
In this case, let me go ahead and check to see if there is a way for you to see the system serial number from the SMBIOS.
I know that the serial number is actually available in the Intel® Visual Bios but this will be the motherboard S/N and not the kit, I guess that you would like to retrieve that information with the System Management BIOS (SMBIOS).
This option was not available in the Intel® NUCs but let me do a research for you and as soon as I get the information I will get back to you.
I forgot to mentioned that I work for Intel Customer Support and I just checked this morning and there is going to be a replacement tool for ITK.
I cant give you more details because this is work in progress but this new tool should be released sometime next year.
I hope this helps,
The SMBIOS strings for the board are always provided. There is a Product ID string and a unique Serial Number string in the SMBIOS Baseboard Structure that you can use to identify each and every NUC that you have. This is consistent across all NUC products. There is really no need for you to fill in the System (or Chassis strings) if you don't want to; you have the information you need without doing so.
Thank you for that information you have kindly provided.
