Retro Raspberry pi 4 DOS PC Tower case

thingiverse

A Retro 386/486 PC Tower case for Raspberry Pi 4 i designed for the Dosbian facebook group. What you need to complete it: * A fullsize HDMI female to Micro HDMI Male * A USB C Extender (male to female) * 40mm 12v fan * 7mm pushswitch * 4 x M3 Screws and bolt for the fan * 8 x 2mm mounting screws for the Pi and lid * A 3.5mm panel mountable audiojack, a 3.5mm plug with cable, some soldering. (for routing audio if needed) * 4 x Female GPIO jumper cable for connecting activity leds. * 2 x 3mm LED, i recommend one green and one red, for activity led and power led in the front. Activity/power led instructions: * Cut of one connector on the jumper wire, keep one female gpio connector on each cable * Shorten legs on LED's and solder the wires. * Connect Power led to GND and GPIO 14(TXD) * Connect Activity led to GND and GPIO 19 * Mount in holes with a small blob of hotglue or epoxy behind. * Add this to the bottom of you /boot/config.txt file: dtoverlay=pi3-act-led,gpio=19 WARNING: Check wich voltage your leds need, the gpio will output 3.3v, you WILL need to add resistor to the postive to your leds if not using blue wich usually are 3-4v. Red and green are usually around 2.3v and will need resistors. 3v to a red or green LED wil burn it! Be carefull with polarity, some led will burn with wrong polarity. Optional: A MicroSD to Standard SD extender with about 15cm flex cable for the floppy like slot, not needed but cool. For mounting the female ports inside the case i recommend epoxy, i might update the design with mounting brackets when i get the cables, but dont hold your breath, if epoxy works fine for me i wont hassle with it. Raspberry Pi 3 and vga666 board designs are coming later on. ***************************************************** ******************* UPDATES: ******************** ***************************************************** 2020-05-15: Added a version with a cutout for a 3.5mm audiojack by request 2020-05-15: v7, Increased the front SDCard slot, it was a bit tight 2020-05-16: v8, added activity and power led to front by request. 2020-05-16: Added a version without powerswitch in front, moved the led to look better without powerswitch by request. 2020-06-07 Adjusted USB placement for better fit, changed the back fangrill to honeycomb should be easier to print and looks better. Added a loose STL for SDCard reader carrige for the front, print and glue in place if you need it. Like my design? use it? Buy me a beer (No pressure) http://paypal.me/johanssonjimmy
