Intel has characterized the "WHEA UNCORRECTABLE ERROR" issue on the Intel® NUC Kits that have been returned to Intel. Intel has released BIOS 0042 which correctly initializes the voltage regulator and eliminates the electrical over-voltage which has been proven to cause the "WHEA UNCORRECTABLE ERROR" issue. Customers who continue to experience the "WHEA UNCORRECTABLE ERROR" issue are encouraged to contact Intel Customer Support.

Intel recommends customers update the Intel NUC to BIOS version 0042. Systems with a product number of SAxxxxxx-503 or later, or systems with a blue dot label added to the Intel NUC and the outer box, have already been updated to BIOS version 0042.

It seems intel has managed to find and correct the issue of WHEA errors through a BIOS update (link)
So maybe they are a good option now?
