ASRock revealed the Z170M-PIO2, which is a micro-ATX socket LGA1151 motherboard with an angled PCI-Express Gen 3.0 x16 slot, which lets you install a graphics card parallel to the motherboard. Which will be perfect for certain PIO form-factor compliant SFF cases and don’t have to use any PCIe riser cable.
The PIO form-factor is an emerging standard of small SFF cases that you mount along the VESA wall-mount bolts of your display. Technically, the board conforms to the uDTX form-factor but is compatible with micro-ATX and PIO form-factors.
The board is based on the overclocking-ready Z170 Express chipset, with two memory slots which support up to 32 GB of dual-channel DDR4 memory. Other specifications are pretty similar to standard ITX motherboards. Like 24-pin ATX and 4-pin CPU power connectors, an mPCIe slot (for WLAN cards), one 32 Gb/s M.2 slot, four SATA 6 Gb/s ports, 6-channel HD audio, four USB 3.0 ports, and gigabit Ethernet make for the rest of its connectivity.
