One particular detail of the NucBox K12 design, however, could certainly use another look. Unfortunately on the GMK system, these thumb screws are small and tight with smooth metal perimeters for extremely poor gripping properties. In fact, loosening the thumb screws on our NucBox K12 test unit would require rubber bands and a monkey wrench. Once the four thumb screws are removed from the NucBox K12, four additional Phillips screws must be removed to even access the motherboard.
