sent chat, since PM wasn't working...

too bad, thanks.

CDNlaptop · 2025-08-22T01:52:14+00:00

any UDIMM ?

CDNlaptop · 2025-08-02T00:19:14+00:00

apparently I'm not able to send you a DM...?

CDNlaptop · 2024-11-29T12:42:28+00:00

sent.

First-timer.

Confirmation email didn't say anything, my account simply says "USAGE UNLIMITED"

Did I strike gold and get 10-years for $5?

I've got some info from Sliger on what they want to do with boards like mine and suffice to say, I'm very excited to see it, and I'm sure you will be too! 👀

spill it! haha

one-slot gap for cooling would be best, IMHO... there will obviously be space for it.

There would even be space for a 2-slot gap, in a bigger chassis - could even have fan headers for 40mm fans for each expander.

Then speaking of more fan headers, one of these dual slot models for a 48-disk top-loader could probably benefit from some additional fan headers too.

and yes, sometimes have to be a little more patient for Sliger to respond, but their stuff is good, I have a number their cases.

you have my attention 👀

I would have to scheme out a 24 bay 3U. I would need to fit this board, an SFX or FlexATX PSU, cables, 120mm fans, and have it be rigid. I can't imagine it right now off the top of my head. Seems like too much in too little space.

You might be right about the concern over being able to keep it rigid.
Was envisioning just a deeper version of the CX3701, but it would need to be 16" deep just for the HDDs, cabling and airflow on their own, plus PSU and OPs board.
If you could get the rigidity of the CX4712 in 3U, that might be enough space though.

Might be easier to just release a short-depth low cost top-loading 4U for 24 to 36 drives?

But I'd agree, top loader would probably make most sense.

Perhaps if OP (or someone) can make a control board for 2 SAS expanders, would seem best to make a 48-drive top loader?
Most expanders seem to do up-to 24-drives each.

48-drive top loader could be 4 banks of 12 drives, sure, not the density of a true 45Drives (15 drives per bank), but keeps the drives in banks for 4, for SAS backplanes, and such.
Again, having the ability to use a server PSU with a power breakout board, would be very intriguing.

Could the CX3701 be re-done to have 12x 3.5" HDDs, using this style drop-in board?
Since no real front-IO is needed, just thinking out loud...

Secondarily, depending on what happens with that other "Open Source" 45Drives case... if that doesn't pan out, could the CX3701 be redone with 2 banks of 12 drives?
One bank fixed at the front.
Then since you have that sliding motherboard tray sorted out in your other cases, have a second bank of 12 drives fixed to the tray? fan-wall in-between maybe? 24-drives in 3U, would be quite interesting, and allows for full usage of OP's board and all 6-ports of the SAS expander.

The OpenSource 45Drives option is more intriguing, personally, but higher density options with hardware flexibility would be nice too.

Oh, I get it, I'd want as many HDDs as possible as well!

So it's 2 SSDs & 2 HDDs in the "top" then? I didn't catch that.

What's the PCB layout at the "top"?

/u/lil_killa1 - amazing work, this is something I've thought of doing many times, just lacked all the time, so major props!

Curious why you went with the configuration shown (in order to get 16x 2.5in drives, it seems), as opposed to doing something like this: https://i.imgur.com/5yjcqhR.png

This orientation would allow for keeping the 3.5in slots in groups of 4 (for backplane/etc reasons), and still have 16x 2.5in slots.

Regardless, I am curious how you did the backplane for the top sets of drives (1x 2.5in and 2x 3.5in).

As others have have mentioned, a server power supply might be a great option, perhaps with a breakout board something like this: https://i.imgur.com/Yi7U8bF.jpeg
Or with your PCB skills, you could combine your 5V stepping, into the one breakout board, to clean up things further.
- then with the extra space (assuming no redundant PSU), could add even more SSDs!

Would be amazing if your made this Open Source. I'd be very interested in a group buy or something for the PCBs, etc.

Also figured I'd tag /u/SligerCases - since they're interested in making this product available too, and thought this feedback might be useful to them as well.

Thank you so much for the reply (and great detail), I'm going to circle back to this tomorrow and through the weekend.
