First up is the GIGABYTE B360M DS3H, a Micro-ATX motherboard with four DDR4 memory slots, one PCI Express x16 slot, one PCI Express x4 slot, one PCI Express x1 slot, and one M.2 slot. This one has DVI and VGA display outputs.
Next we have the GIGABYTE B360N WIFI, this is a Mini-ITX motherboard with two DDR4 slots, one PCI Express x16 slot, and onboard WiFi AC. The board likely has one M.2 slot but that feature is unconfirmed.
