Seems like an excellent choice for anyone looking to build a low-power server-router. Intel N100 has quicksync transcoding for a Plex/Jellyfin Media Server, and 4x2.5GB Ethernet Ports is perfect for a pfSense VM. 6x SATA ports and 2x M.2 slots affords you plenty of storage too.
Run xcp-ng on this and you get the best of both worlds.
In my opinion this is the smarter money purchase than the Chatreey NAS that got posted because it has 4 ethernet ports and much greater potential for storage for a lower price. All that's missing is a case, but a bit of DIY or browsing Gumtree can take care of that.
[Edit] It has come to my attention that 5 of the 6 on-board SATA ports for this motherboard are bottlenecked for some reason. They cannot reach the maximum SATA transfer speed.
If you prioritize NAS performance consider the Intel N5105 Version for $166.39:

The N5105 does not have bottlenecked SATA ports and is $25 cheaper, but you lose the PCIe 3.0 x1 expansion slot.
This doesn't seem to come with any IO Shield?
