The GIGABYTE H370 AORUS Gaming 3 (WiFi) is world's first H370 motherboard to leak online, specifications and photos hit the web yesterday. This motherboard will be officially released early next month, alongside Intel's second wave of Coffee Lake processors.
The H370 AORUS Gaming 3 has two PCIe x16 slots, four PCIe x1 slots, and two M.2 slots. Unlike what the photos depict, it appears the motherboard's PCB is not black but a very dark shade of brown. One M.2 slot is covered by a headspreader and the southbridge, memory slots, audio chipset, and I/O are all equipped with RGB LED lighting (which can be deactivated).
WiFi is provided by an onboard module, which is connected to a Mini PCIe slot that is located under the secondary PCIe x16 slot.
