MSI TRX40 PRO WiFi Schematic
A wide range of connectivity is provided as well: seven standard USB ports, one of the new USB Type C, dual gigabit Ethernet, WiFi, Bluetooth, and both analog and digital audio. Internally it has eight SATA ports and two M.2 connectors, with included heatsinks, allowing for a flexible array of storage options.
It is unfortunate that this motherboard doesn't support quad GPUs, but for many applications the new Threadripper processors are amazing - and many of the programs where it excels don't need multi-GPU support anyway. This board also does not support TPM, so just a heads-up for anyone who needs that.
