Neither do we because we do not know how these 9 SATA ports (weird number…) are wired (chipset, or external controller). The 2.5 GbE NICs are not great (all of them). There’s no IPMI. And I would not be fully confident about ECC support, not to mention finding ECC SO-DIMM.
In short, there’s nothing I like about this board.
Is mini-ITX size important?
For low power, go Atom C3000 or Xeon D-1500.
C3558 up to 8 drives (Supermicro A2SDi-4C-HLN4F).
C3758 up to 12 drives (A2SDi-H-TF A2SDi-8C-HLN4F).
Beyond 12 drives, D-1500 and a SAS HBA. For pure storage, a D-1508 or D-1518 would do; get more cores if the NAS is to further run aps/VMs. An all-in-one solution would be a Supermicro X10SDV-4C-TP4F (-TP8F) or AsRockRack D1541D4U-2T8R (-2O8R); otherwise just any X10SDV board and a HBA card.
