Who doesn't want a -CB3?
I BO'd $48 on this -CB2 listing, might be able to get lower.

That would be the rough equivalent of the CB1/2, not the CB3 which has IPMI. Well, not really, because CB1/2 provides front panel controls.
I'm dumb when it comes to electric diagrams but can't you actually just power pi directly off the PSU(there's ton of free 5V connectors available), and just use the single pwm cable and split that with a breadboard to all 3 fans, no? All of the components will have a common ground so I don't see any problem with that?
In my particular cas i use 837 and it has 3 fans that are very annoying at most of their speeds, plus the enclosure likes to speed them up and down so I decided to unplug PWM but that still didn't help, it seems like it's now controlled by the voltage. So i connected the fans directly to 12v and that worked. I still left all 3 yellow wires(tachometer signal) so that i can also monitor if fans fail(with sg_ses). That of course means fans are running full speed but this is actually necessary by the setup to cool all the disks and also results in a higher frequency noise that is easier to mitigate actually than mids.
It should be doable, though I'm not sure if anyone has figured out the software side of things since you'd need to run an IPMI server and have everything hooked into that correctly.
Whats your budget for the jbod board?
I might have two to sell in a couple weeks.
For the mounting plate i would recommend to just 3dprint sth (or let print if you dont have your own)

You don't need it, but it's nice to have an already-standardized protocol you can work with. If everything else in your homelab is using IPMI, it's nice to be able to manage everything with one client.
I think I have a spare mounting bracket I'm not going to use, reach out if you end up needing it.
The network cable and rear HP/LP mount for it are sold separate, fyi.

Wait, is it actually possible to power a mobo without a CPU/memory and use it as a jbod? I thought most motherboards wouldn't power on without a CPU/memory...I've never tried without really.
yeah, not all mainboards, but most of the supermicro boards can do it.
Problem with this solution is that the mainboards take up a lot of space compared to the cb3.
I did several conversions of intertech mining cases and with the cb3, i am able to fit 50 disks easily with more space between the drives to keep temps and noise down, even with sth small like a micro atx i would loose at least the last two rows, which would bring that down to more like 35 disks with similar spacing and a lot of wasted space.
But yeah around 190€ each is not cheap.
