Intel hasn't lifted the curtain on the its next-gen Skylake processors, but motherboards designed for them are popping up at Computex this week. ASRock's pint-sized Z170 Gaming-ITX/AC looks like it strikes a nice balance for small-form-factor PCs.
The board has the requisite PCIe x16 slot for graphics, plus full-sized DIMM slots for DDR4 memory. Six SATA ports are plainly visible, two of them part of a SATA Express connector. The spec sheet also lists an "Ultra M.2" slot that's likely mounted on the board's underbelly and linked to four PCIe Gen3 lanes.
Despite the board's gamer branding, there's no Killer hardware in sight. The Gigabit Ethernet controller and 802.11ac Wi-Fi card both come from Intel. The requisite Realtek audio is backed by DTS Connect, which can encode multi-channel game audio for digital output. Around back, you get Type-C and Type-A USB 3.1 ports along with a selection of traditional USB 3.0 fare.
ASRock's Z97 Mini-ITX boards are very affordable, so I wouldn't expect this one to break the bank.
