With a 13.9 L case, the NUC 13 Extreme is larger than most builds that support a desktop-grade GPU. Intel decided to provide even more room so that users can fit a 3-slot GPU, plus improve airflow. The "Raptor Canyon" will support up to i9 K desktop processors with up to 64 GB of DDR5 RAM and Intel is expected to unveil the full specs in two weeks.
