https://www.techpowerup.com/244107/asus-intros-prime-h310t-motherboardASUS rolled out the Prime H310T, one of the rare few thin mini-ITX motherboards based on Intel 300-series chipset, a boon for certain SFF cases such as the Akasa Euler series, or DIY all-in-one PC upgrades. Based on Intel H310 chipset, the board supports 8th generation Intel "Coffee Lake" processors (including 95W TDP chips). It draws power from 2-pin (12V DC in), and conditions it for the LGA1151 processor using a simple 3+1 phase VRM. The CPU socket is wired to two DDR4 SO-DIMM slots, which support up to 32 GB of dual-channel DDR4-2666 memory.
Oh boy! Even though it doesn't have a PCIe 4x slot it does have the M.2 4x slot so there are GPU options for us.
I'd love to snatch up one of those if only to be able to go 6-core in the future on Thin ITX.
