DIY NAS Build Review

TrueNAS General
1

I’m looking for advice on this DIY NAS build. I have a 3 node Intel NUC Proxmox cluster running the following containers:

  • Immich
  • Jellyfin
  • Paperless-NGX
  • Navidrome
  • Mealie
  • Actual Budget
  • plus whatever else I will find between now and the NAS purchase

Each NUC has 4TB of storage but with Immich/Jellyfin/Navidrome it’s not a long-term solution. The NAS would be storing the data for these containers only, the containers themselves would continue to run on the NUCs. I plan to run TrusNAS Core with 8 12TB drives.

  • Lowish Power Usage - all transcoding for video/music/photos will be done on the NUCs
  • 10Gbe networking - the NUCs support 2.5Gbe so wanted the build to support at least 2.5Gbe

Build:
CPU: Intel i3 9100
Motherboard: ASRock Rack E3C246D4U2-2T
Memory: 2x Kingston ValueRam 16GB ECC
Boot Disk: Kingston NV3 250GB M.2 2280 NVME
Case: Audheid K7 8 Bay
Power Supply: Supermicro PWS-351-1H

Any potential gotchas with this build? It looks like I’ll be able to get many of the components used.

Looks fine, and you could even transcode on the NAS (C246 + iGPU).

Does the motherboard support M2 and 8 SATA at same time. Docs look otherwise?
see SATA/SAS Storage section with notes

https://www.asrockrack.com/general/productdetail.asp?Model=E3C246D4U2-2T#Specifications

- 8 x SATA3 6Gb/s (SATA0-7, SATA_0 supports SATA DOM)
- 7 x SATA3 6Gb/s (SATA1-7) and 1 x M.2 SSD SATA connected*

*The M.2 slot (M2_1) is shared with the SATA_0 connector. When M2_1 is populated with a M.2 SATA3 module, the Pin 7 of SATA_0 is disabled.

Yes, it does. That only applies to M.2 SATA SSD, not M.2 NVME SSD: https://www.reddit.com/r/unRAID/comments/14punfj/asrock_rack_e3c246d4u22t_fan_control_questions/.
