Positioned as a high_end HEDT board in a tiny footprint, it exists to bring LGA2066 capability to small‑form‑factor builds. It suits ITX rigs needing quad‑channel memory and multiple NVMe drives: four DDR4 SO‑DIMM slots (up to 64 GB), three PCIe 3.0 x4 M.2, Intel 802.11ac Wi‑Fi, dual Intel GbE, USB 3.1 Gen2 Type‑A/C, plus one PCIe 3.0 x16 for a full‑size GPU.
