Last year I built a nas system around the Asrock j4105 itx board, using a flashed dell perc h200 as an hba, in a fractal node 304. I had looked at arm options, including the kobol 64 and boards from hardkernel, but decided that paying a bit more for x86 would make things a lot easier. It's working well so far: low power draw and near silent, allows for proper zfs on linux support, hardware accelerating transcoding for Jellyfin streams, and at a bit over half the cost of a 6 bay x86 Synology.
