Photos hit the web of the MSI H310-F PRO, a new motherboard for cryptocurrency miners. This seems to be the first mining motherboard for the Coffee Lake platform. The board has twelve PCI Express x1 slots plus one full-sized PCI Express x16 slot, enabling the installation of up to 13 video cards with the use of PCI Express risers.
There are two DDR4 memory slots, Molex connectors for additional power to the graphics cards, and four fan headers. Pricing is unknown.
MSI H310-F PRO motherboard has space for additional 5 PCIe x1 slots, but due to chipset limitations, those are unavailable (they are likely to be utilized by B360-based motherboards).
