The very first Xeon NUC

Quartz Canyon is Intel's upcoming diminutive NUC workstation. Powered by either a Xeon E or an i7 vPro processor this turbocharged NUC features a PCIe x16 slot for a discrete graphics card. The case itself is very similar (identical?) to the more consumer-oriented Ghost Canyon NUC that we previewed last year. Quartz Canyon is actively-cooled, but passive solutions are always possible.
