ASRock Develops Mini-ITX LGA2011v3 Motherboard with Quad-Channel Memory
 

They've done it! After building the first LGA2011v3 motherboard in the mini-ITX form-factor, letting you cram up to 8 "Haswell" cores into a lunchbox-sized PC, albeit having to make do with just dual-channel memory; ASRock developed the first mini-ITX motherboard with not just LGA2011v3, but also its full quad-channel memory interface, called the EPC612D4I. There's just one rider, which shouldn't really be a dealbreaker - this is a server-grade motherboard, and is bound to be expensive.

The EPC612D4I achieves its quad-channel memory chops by using smaller DDR4 SO-DIMM slots instead of standard-sized DIMM slots. Availability of aftermarket DDR4 SO-DIMM memory is close to non-existent, but that could change with 6th Generation Core processor notebooks hitting the shelves by Holiday 2015. As an enterprise board, it also supports Xeon E5-1600 V3 and E5-2600 V3 processors.
