Newegg offers the ASRock Z170M Extreme4 LGA 1151 Intel microATX Motherboard
for shipping. That's the lowest total price we could find by $26, although we saw it for $3 less in April. It supports up to i7 processors, 4096x2304 resolutions (4K UHD), and 64GB RAM. It features three PCI Express 3.0 x16 slots, six Serial ATA 6Gb/s slots, one M.2 socket, four rear USB 3.0 ports, USB 3.1 Type-A and Type-C ports, HDMI, DVI-D, and Gigabit Ethernet.
