ASRock has announced a new mini-STX motherboard with an interesting twist, as the H110-STX MXM motherboard offers support for current MXM (version 3.0b, up to 120W) mobile graphics cards.
Like the ECS H110 motherboard featured in our recent Mini-STX build, the ASRock H110-STX MXM is based on the LGA1151 socket (though CPU TDP was not in the source post), offers a pair a DDR SODIMM slots for up to 32GB of DDR4 notebook memory. Storage support is excellent with dual SATA ports and M.2 SSD support. Importantly, this ASRock board uses PCI Express 3.0 on both the MXM (PCIe 3.0 x16) and M.2 (PCIe 3.0 x4) slots. Display output capability is excellent as well, quoting the TechPowerUp post:
"Display connectivity includes one HDMI port that's wired to the CPU's onboard graphics, a second HDMI port wired to the MXM slot, a full-size DisplayPort wired to the MXM, and a Thunderbolt port with mini-DisplayPort wiring to the MXM."
There are some roadblocks to building up a gaming system with this motherboard, not the least of which is cost. Consider that compatible MXM 3.0b options (with a recent GPU) are hundreds of dollars from a place like Eurocom (a GTX 980M is around $800, for example). Naturally, if you had a damaged gaming notebook with a usable MXM GPU, this board might be a nice option for re-purposing that graphics card. Cooling for the MXM card is another issue, however, though harvesting an MXM card from a notebook could potentially allow implementing the existing thermal solution from the laptop.

Update: We now have full specifications from ASRock's product page, which include:
- Socket LGA1151 for Intel Core i7/i5/i3/Pentium/Celeron (Kabylake)
- Supports MXM Graphics Card (Type-B , Up to 120W)
- Supports DDR4 2400MHz, 2 x SO-DIMM, up to 32GB system memory
- 1 x HDMI (4K@60Hz), 1x HDMI, 1x DisplayPort, 1x Mini-DisplayPort
- 3x USB3.0 Type-A, 1x Thunderbolt 3 with USB 3.1 Type-C
- 1x M.2 (Key E), 2x M.2 (Key M)
- 1x Intel i219V Gigabit LAN
- DC 19V / 220W power input
Of note, the chipset is listed as Z270, though the product name and primary motherboard photo suggest H110. The H110-STX MXM is part of ASRocks industrial motherboard offerings (with signage and gaming the mentioned applications), and includes a 220W power supply. Pricing and availability were not mentioned.
