These are super versatile boards w/ dual 10GbE that support Coffee Lake CPUs (e.g. Core i3/i5/i7/i9-8000/9000 or Xeon E-2100/2200), DDR4 UDIMMs (ECC or non-ECC), and Quick Sync Video (Intel QSV). It's a great opportunity to build a storage, virtualization, or media server out of spare desktop parts.Includes motherboard, I/O shield, M.2 screw, and 2x SATA cables.E3C246D4U2-2T
