Downsizing from Ryzen 5700X/X570 to N5105 for Unraid NAS - Seeking advice on DIY Case & Power
Hi all! I've been running a home NAS for a while, and it has gone through several hardware revisions. My current setup is:
- Case: Node 804 (6 fans)
- Mobo/CPU: AsRock X570m PRO4 + Ryzen 5700X + 32GB RAM (leftover ASM1166 PCIe)
- Storage: 4x8TB + 3x4TB 3.5" HDDs + 64GB NVMe for Docker
- OS: Unraid
- GPU: Radeon 6600 (initially for VM gaming)
- Currently most of the time used with WinToGo SSD for Sunshine/Moonlight streaming to Steam Deck
The Problem: I think it's an overkill. Since modern anti-cheats make VM gaming risky, I mostly use it as a bare-metal Windows machine for streaming games. My media is handled by a separate S905X board (Armbian), so the NAS only really runs a torrent client. It's noisy, draws power.
The Plan: I want to downsize to a fanless N5105 mini-PC (BKHD 1338NP https://bkhdpc.com/zhuban/43.html ) for the reason to reduce noise, space and power consumption and remove the need to shutdown the NAS to access the data while the 5700x machine handles a game.
It came in a aluminium case and I modded 2 gpu fans on top of the heatsink with a temperature and rpm controller.
- Specs: N5105, 2x SO-DIMM (1x16GB installed), 1x SATA, 1x M.2 (PCIe x2).
- Storage Mod: Buy and use an ASM1166 M.2 to 6x SATA adapter + the internal SATA port to get 7 ports total for my Unraid array.
The Challenges:
- Power: The stock 12V 4A (48W) probably brick won't handle the spin-up current of 7 HDDs. I’m considering using a spare ATX PSU (FSP 450W) with PS_ON shorted, or a PS3 12V 16A PSU. (If I go with the PS3 unit, I’ll need to add a DC-DC step-down for the 5V rail).
- Case: I’ll need to 3D print or DIY a custom enclosure (presumably from aluminum to hold the 7 drives, the PSU, and the N5105 board with the bottom case removed. 2x120 fans should be enough for the drives.
Questions:
- Have I missed anything?
- Is there any pitfalls why this might be a bad idea?
Thanks in advance!
