We're currently sampling the i5 version of Tranquil PC's Rugged Intel Core Mini PC, and so far so good. Upgrading the RAM and storage is not the easiest since the motherboard has to be completely removed from the case, but cooling is nothing short of amazing. The case itself is as heavy as the Akasa Euler (designed for 35W processors) and keeps the 15W i5-7200U systematically under 50°C.
