With the EAC Mini, Winmate is trying a different approach. It's based on a modular system where a basic configuration contains the motherboard and a standard minimal complement of I/O in a very compact box. Note that the basic EAC Mini system module with its dual RJ45 LAN jacks, dual USB 3.0 ports, and HDMI connector always sits on top of a stacked configuration. That's because the system module contains the heatsink/spreader that dissipates heat from the processor and ancillary motherboard electronics. No fan needed.
