My PiNAS project, part yeeha, Design complete (essentially). Afternoon update

This is the last print before the final ABS print and nickel coating. (Sever case will be ABS, backplane case is ABS with PC ears)
All up and running :D

Since I get asked a lot about my intentions and motivations I'll put this here:

This took a year longer than I'd hoped for, but I'm essentially done with the production design. The lid needs some small adjustments, but those can be added to the final print. I have the parts for a power sequencing circuit, but since the issue that that solves is mostly cosmetic (lane errors during reboots only) I left that out for now. I can easily add it inline with the external power cable later.

The abs will be gray, but the translucent natural PLA has been neat.

This is just a test rack I setup. The production rack is 6U, deeper, and enclosed.
The tape is just temporary until I make the aforementioned lid adjustments

Inside. and a very ripe scale

Something I added for the PCIe switch. With its small heatsink, an individual fan worked better than pulling air over it with the exhaust fans.
It's an Adda branded, 5v 40x10mm
I toyed with the idea of some kind of heatsink attachment, but this was much easier. It's a separate part that I just solvent welded to the case.
Runs off the Pi's 5v because it was convenient

I was hoping I could capture all the little drive noises but the phone camera amplifies the fan noise too much. It's about 60% less wooshy in person lol

The plan is 12 8TB with 2 parity drives. I'll be adding drives as I can afford them (thanks to the new raidz expansion feature). I currently have 5 8TB and a few smaller. The backplane can be daisy chained and I have 2 more, so I could get ridiculous with it ;)

All the temps that I can read are within a comfortable range
