6" Rack, Raspberry Pi 3 Model B - ATX Input

thingiverse

A cabinet for KronBjorn's 6" rack: https://www.thingiverse.com/thing:1936196 Intended to be used with my ATX PSU cabinet here: https://www.thingiverse.com/thing:3352702 Made to house a Pi 3 with an ATX 24 pin power input, I'm intending to power the Pi off of the 5v standby pin and have the Pi turn the ATX supply on via GPIO. I designed this to be mounted upside down in the rack, so the wires going to the ATX plug don't lay on top of the Pi. Here's the pinouts for the ATX supply: http://pinouts.ru/Power/atx_v2_pinout.shtml Make sure your PSU outputs enough amperage on the standby rail, older ones only output a few mA, newer ones a couple of amps. My Corsair CX650 I intend to use outputs 3A on standby, plenty for a Pi. https://ebay.us/BbGxdH Here's the panel mount 24 pin Mini-Fit Jr plug for the ATX supply. https://ebay.us/yuKqJj And here's the male pins. You'll need to crimp the pins onto a microUSB pigtail to power the Pi, and another to the signal line so the GPIO can ground it and turn the PSU on. Do your research to make sure the signal line isn't going to draw too much current. Use a multimeter and measure the mA between the signal wire and ground, you may need a MosFET between the signal line and the Pi. There are special crimpers for Molex pins, but you may be able to use a standard pair. YouTube is your friend here if you've never done this. Also included is my remixed Pi 3 light pipe adapter. This has 1.9mm holes so clear 1.75mm filament can be used to transmit pwr and hdd lights to the front of the case. https://www.thingiverse.com/thing:3352721 The front takes a 40mm fan, and has two 1.8mm holes for the clear filament light pipes from the Pi. I'm almost certain 1.8mm holes will be too tight to press 1.75mm filament into, this will be updated after I try it out. Handles can be found here: https://www.thingiverse.com/thing:1957436 The cooling vents on the top are offset due to the Pi's placement, but they should still provide adequate airflow. 01/18 Found an old 20 pin ATX connector with the panel mount tabs that had enough depth for a 3mm panel even though Molex specs say 2mm. So I uploaded Back-HeavyDuty-3mmATX version of the back panel, this one is 3mm thick and doesn't include the recess to reduce to 2mm thickness where the ATX plug locks in. 01/24 One slowboat made it with my screws and 40mm 5v Noctua. Pi3B+ fit fine, fan fit fine. Those are the self tapping screws that came with the fan, fit fine in the countersinks, don't protrude. The Noctua came with a 3 - 2 pin adapter that plugged nicely onto the GPIO where there's a 5v and gnd right next to each other. I used 6mm screws on the Pi but I had to use old PC motherboard fiber washers under the heads because without them the screws protruded just a bit. You could trim the screws instead. The corner with the light pipe bracket got a 10mm screw and it fit fine, the holes seem to line up over the LEDs.
