Hello,
I am looking to build a FreeNAS server. One of the potential builds I am looking at uses an ASRock H170M-ITX/ac motherboard. Under the specifications for the RAM (http://www.asrock.com/mb/Intel/H170M-ITXac/?cat=Specifications), it claims "Supports ECC UDIMM memory modules (operate in non-ECC mode)". I was wondering if this would be suitable to use in a FreeNAS server, or if it would be no different than running FreeNAS on non-ECC RAM.
Also, I would love to hear any other recommendations for a Mini-ITX motherboard. FreeNAS will be a VM running on a Citrix XenServer hypervisor alongside other networking-centric VMs. ECC support is obviously a need. Preferably, the board should also support M.2 and integrated graphics, though both are optional.
Thank you very much for your time!

Probably a bit overkill on the CPU side - but this is a seriously beefy 64GB system ....
