Pi NAS (Raspberry pi 3 B+ with 2 x 3.5' HDD's)
Description
I designed this Raspberry Pi NAS to connect two 3.5' HDD's to a Pi 3B+. There is a DC buck converter for the Pi so you don't need to have a separate 5v power supply. With the current design, you will need to drill three holes into the Pi case to screw it to the HDD enclosure. I'll update the design in due course. [Here is a link](https://github.com/thatguy-za/raspberrypi_controller/blob/main/controller.py) to the code that I wrote so you can use the buttons to shutdown and reboot the Pi. I've tried a few different operating systems on the Pi and have settled for raspberry pi OS 64 bit but something like OpenMediaVault would work very well too.
