Previous phost[1] After I realized I could repurpose the power supply, it got my mind working. I decided that I would need to add 2 female USB ports and 2 ON/OFF switches to the case. Luckily, I had those items in my stash of electronic components. Soldering is one of those things that I enjoy doing, but it takes me awhile, especially since I don't do it too often. I had to make 2 circuits, which basically looked like this: +5V wire from power supply -> terminal block -> ON/OFF switch -> USB jack > terminal block -> -5V wire from power supply Since I get freaked out when doing anything electrical, I did a 5 volt USB LED light "hello world" circuit test with an external USB 5 volt battery charger, breadboard, and jumper clips. Good thing I did since I had the pinout reversed on the female USB jack. Here's a pic.[2] After that I soldered the circuit together, crimped terminal connectors to the wires from the power supply, and put in the terminal block. Then I had to drill 2 holes in the front of the 1U case for the 2 ON/OFF switches. Here is a pic of the switches mounted to the case. [3] For sanity's sake, I did another LED "hello world" circuit test with the power supply, first with a battery with AC power and then wall power. Another pic.[4] Then I mounted the 2 Raspberry Pi2's and 2 WD Pi Drives. Western Digital used to make Raspberry Pi drives and accessories under their WDLABS project, which is now defunct. I picked up some drives, cables, and a case during their fire sale. They had a tailor-made cable that allowed you to connect the Pi and the drive using 1 microUSB cable, which is mounted in the 2 USB jacks. Here is a pic of the case with the Pis. [5] For the Pis, I used openmediavault[6] for both NAS servers, which I have used in the past and had no problems. Here is a pic of the NAS booting up when attached to mains power. [7] After that, I tidy'd the cabling and closed her up. Obligatory decals were added to cover most of the unused holes from the switch. I also included 2 USB extension cables to each Pi for attaching external storage and backups without opening the case. Here's the front panel pic.[8] Here's a pic of the 1U Pi NAS mounted in my desk. [9] The Pi works out pretty good for now. There are other modifications I would like to do, but kept those for another time. Overall, I had fun putting this together. I probably should take more breaks, especially when soldering and also remove my contacts when I solder since I am myopic. Good thing that Raspberry Pi 2 is good enough for this project since it doesn't use as much power as the newer Pis. I should run some tests. Also, the way I put it together makes it easy to repurpose if/when I need to put different devices in the case.
