My PiNAS project, part 44, external DC power out

Prev: https://imgur.com/gallery/m4iv6b9

The 1U server section of this system doesn't have an AC power supply, but the 2U SAS backplane does. Since the BP's PSU has plenty of headroom, I figured I may as well power the server section with it.

These panel mount "aviation" connectors fit the bill for the expected current.
12v, 5v, and 2 grounds, 14AWG x4
The server section contains the RPi5, 3 SSDs, and 3 slot powered PCIe devices (Switch, HBA, NIC).

I'll be adding the hole to the final 3D models, but for now I just added it manually. No 15mm drill bit so I just traced the connector, then used a soldering iron and blade tip to cut/melt the ABS. The tip can be cleaned with acetone
