Possibly the best Computex news yet: MSI is working on a fanless Kaby Lake barebone. Powered by the 15W U-series processors (from Celeron up to Core i7) the Cubi 3 will feature 6 USB and 2 Ethernet ports, M.2 and 2.5" SSD support, and a massive internal heat sink.
The Cubi 3 production starts in August for an early fall launch.
