Retro Raspberry pi 4 DOS PC Tower case

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.
