Fanless NAS (lemmy.world)

Hi I got a very specific recommendation request:

I would like to build a fanless rackmount NAS for my homelab. Fanless because I am sleeping next to it. So to achieve that I don't want any moving part, hence SSDs and fanless cooling. Rackmount So I can neatly store it in my rack. Ideally I want to run Truenas on it and be not fendor restricted so I cam expand and modify it myself. So I thought about getting a maybe 2U maybe higher case. But here starts my trouble: I want it to support at least 6 external drives and consumer tower PSU because industrial server PSU are not build to be silend. I hope you guys can follow me.

TL;DR: I need a 2U rackmount case with 6+ (4+) external drives and supporting consumer PSU (fanless Design) for a NAS. No pre-build or at least easy modifiable.

Please ask any questions or ask for any infos you need :) Thank you for your time.

I am looking into something similar. Sharing some thoughts here.

Use a low power CPU and a passive cooler
Or, use mainboard with passively cooled on-board CPU
Go all-SSD, HDDs need more power, need more cooling and produce noise
Use a Pico-PSU and an external power supply brick
Or, use a fan-less PSU

Your best bet is going to be a 4U chassis. You can get 2U chassis with consumer PSUs, but they are going to be more expensive and very limited in terms of parts that will work. You can easily find 4U chassis that support regular ATX internals with proper mounting holes for the PSU and mobo standoffs.

There are some small SuperMicro servers that use Xeon-D (I think? Very low power Xeons that are passively cooled), but you're pretty vendor locked in with those.

Do not use external drives for this. TrueNAS doesn't support it, and you'll be limiting your speeds to that of the USB bus, which is not nearly as fast. Pointless going SSDs if you are using external drives.

Where are the external drives living? Hard drive make their own noise. Might consider going with solid state if you want silence.

One example of this that’s making the rounds: https://www.asustor.com/en/product/FS67

Those machines have a fan at the bottom of the case.
