I would imagine there would be no need to build that, plenty of them exist already. It could even be bring-your-own so people could do 2.5" drives or 3.5" drives.
Something like this is $50: https://www.newegg.com/Product/Product.aspx?Item=N82E16816132037
But to concur with your point, at 5L and almost silent losing out on hot-swap might be worth it.
Hi, current ITX NAS user chiming in here. Current build is in a Node 304 (see signature).
1) 3.5" HDDs are still king if you're going for a real NAS. However, the 2.5" HDDs are coming up fast and for archiving type storage (Plex, etc.) that may be suitable. I think a SFF NAS solution should have good parity between using both 3.5" HDDs and 2.5" HDDs. I'd like to be able to switch out 3.5" HDDs for 2.5" HDDs in my Node 304, but the drive cages don't support that.
2) I'm not sure I've seen a 'normal' ITX motherboard with more than 6 SATA ports - there are definitely some specialized boards out that that can support more but they are few and far between. So aim for 6 drives?
3) I think hot swap bays are way overrated. No need.
4) Probably a niche of a niche, but having a spot to stick an internal USB drive with the OS would be nice. Some motherboards even have a type-A header built into the board, but having a USB sticking out the back is kinda dull.
5) Realistically can you power six 3.5" drives with a power solution smaller than SFX?
I'm thinking of 4x 3.5 and 2x 2.5 as a starting point.
The unas case is still quite big at 8+ liters but does offer hot swap.
You'll need a custom dc board to supply power to the 3.5 but it's not difficult to spec. Just an additional 5V rail.
If we can find 20 interested people it is very possible to do this. I may also look into anything available off the shelf.
This already exists as a case, check out the Silverstone CS01-HS. It is 14 liters but it's tall with top loading drives.how about pure 2.5 hdd NAS? with hot swap please
The Synology is a garbage atom CPU that won't do much Plex transcoding or run any VMs. As you said later, the advantage is bringing your own hardware and especially software. I don't want to use off-the-shelf NAS software (especially the ones with software RAID) because it stuff goes south it's hard to fix. I've been running this HP MicroServer for the last 5 years, it's also 14L in size but I can roll my own OS and PCIe cards. But I'm looking to go Xeon D, and while the SuperMicro chassis is tempting, it's big and pricey and not passive from a PSU standpoint. But that's currently where I'm leaning. It, also, is 14 liters.You're right that it be hard to compete with the synology.

You're already at $400, only 50 short of the synology.
Perhaps like you said, a pure 2.5 based solution, maybe using the 5.25 format.
Though going with a custom solution does allow you to bring your own hardware. Perhaps some people prefer using an i7 to do transcoding work in addition to running a NAS.
The issue with hotswap is you need a high number of minimum order if you want it to be custom.
The thing with 2.5 inch disks is the limitation in disk size. There is only one brand (which i personally like to avoid) that offers 5TB which is Seagate.I would love to get 2.5 inch based NAS and bring hardware of my choice.
it would be much better if mounted 2.5 drives (not hot swappable) could be taken out without unmounting the rest of the drives.
how high is the minimum order number would be?
7mm is the height of modern 2.5 2T drives, there 4-5T drives available that have 15mm height.
if we look at desktop hardware + some good controller on top, maybe we can take mITX board with pci-e controller like LSI 9280 via raiser (to lie on motherboard)/on top of m2 drive as they regularly mounted next to pci-e slot or find some board with lots of SATA connectors.
probably maximum sane amount of drives to accommodate is 8. it is from from LSI 9280-8i + we have whatever is motherboard offers.
if we look at the server grade hardware, https://www.supermicro.com/products/motherboard/ATOM/ something like this should fit. mITX and 12 SATA ports + whatever we could/want to utilize fitting reiser + external controller like 9280 inside.
I think it is good idea to make a case:
- with size of mITX board + picoPSU on one side
- with mounts for 2.5 hdds at the side.
- side with mounts for 2.5 hdds has to be built around height of 40MM Noctua fans to blow through 2.5 hdds.
- 2.5 hdd mounts would have place to either mount 15mm drive to have enough to accommodate two 7mm drives instead.
sorry if I am going way too far with that one, seems like it is touching sensitive subject for me - personal storage. can't just pass by
I've done some research and things like the Dynamo 360 or HDPlex do have enough 5V power to run plenty of 3.5" drives. The PicoPSU might not, but there are now things like the HDPlex 200 which do 10A bust 7A sustained on the 5V rail, which should be enough for lots of 3.5" drives since they use 12V for the motor circuitry and 5V for the circuit board, which means the most power hungry part is on the 12V rail which generally has a lot more juice in these DC-DC board scenarios.When going to 3.5 inch a pico-psu might not be an option since it would exceed the power draw at spin up.
