I’m building a NAS for the first time on my own, so I wanted to share the story so far here.
I’m not a stranger to custom builds, in fact I don’t think I ever bought an assembled PC (not counting second hand 386 box a million years ago). But this is my first small, low power build, so it’s not perfect, I already ran into a wall (more later).
I base the build on an AsRock mini-ITX board, the CPU is included, it’s passively cooled, low power consumption but still powerful for a NAS. I’m sticking it into a Node 304 Fractal Design case. Here’s the full list of parts I got:
- AsRock J4125-ITX board with a Celeron 4125 (4-core CPU)
- 8GB DDR4 RAM (a Crucial kit)
- a 500GB NVMe SSD (which I can’t use)
- a couple of Seagate IronWolf 4TB drives
- 90W PicoPSU and some no-name power brick
- Fractal Design Node 304 mini-ITX case.
I planned to have an SSD for OS, these two disks for my photography and media, and then later on expand with more storage (preferably SSD, when I can afford it).
As mentioned, I messed up: the M2 slot on the motherboard is a “Key E” slot. I never bothered with these keys before, so I didn’t know that a Key E slot does not have a SATA protocol, it won’t take my SSD.
Another thing, the PicoPSU is a 20-pin power supply, and the board has a 24-pin slot. It should still be fine, the specs say that this is still okay, but I’ll have to see. According to my back-of-the-napkin calculations, 90 Watts should be enough power for the mobo and CPU, the SSD and the two spinning disks.
Anyway I’ll get a regular SATA SSD tomorrow and see how it’s shaping up. Let me know if you want me to post more on my progress/end result or if you have any questions.
To people negging about the CPU being under powered:
File sharing, media management, a couple of services for a handful of clients… It’s perfectly fine.
At 10W in with a tiny footprint it’s great when you don’t need any more computing power and next winter electricity bill drops.
Not everybody needs a full racks of decommissioned Xeons and arrays on arrays of RAIDs that draw juice like an industrial fruit press regardless it’s in use or not.
Yep, that was my intention. First, it’s low power, so it can be always-on with only a small impact on the power bill. Second, it’s only gonna serve a few things - my photography hobby and media library, and maybe a service or two will come with time. If I need other services, I put them on a Hetzner box and they’re much better taken care of.
I’ve done my share of sysadmin work and even a bit of server-room maintenance, I don’t want a full-time, or even a part time job. This is mostly gonna sit in the corner, and be quiet. If the prices matched, I would have probably just gone with QNap or Synology, but this way I get the NAS and the disks for the same price.
