ASUS productively utilized the scarce real-estate of the mini-ITX PCB - a sizable portion of which is consumed by the heatsink - providing two DDR3 SO-DIMM slots, a conventional PCIe x1, an mPCIe with mSATA pins, two conventional SATA 3 Gb/s ports, and a healthy mix of modern and legacy connectivity, that includes headers for LPT, an RS-232 COM at the rear panel, a mixed-mode PS/2 port, one USB 3.0 SuperSpeed port, a number of USB 2.0/1.1 ports, gigabit Ethernet, HDMI, D-Sub, and 6-channel HD audio. The board is driven by AMI UEFI BIOS.
