Industrial PC we often use in our CNC projects. It has passive cooling. Which is perfect for CNC, since there is always dust and chips that could get into the fans, and then block cooling. With the Intense PC these issues are over. Also it has a SSD disk, so no moving parts that can break. We have often seen hard disk failures on CNC machines due to vibrations. Thats why we have an SSD disk in this PC, no moving parts means a much lower chance of failure due to vibrations.
