Retro Desktop PC Raspberry Pi case

This model is now outdated. Check out V2 here!

-----------------------------------------------------------------

Retro Desktop PC style case based on an old 286 PC I grew up with. Designed to fit a Pi 4B with a 3.5 inch HDMI MPI3508 LCD display. 

In addition to the print you'll need:

• Raspberry Pi 4B
• 3.5 inch HDMI MPI3508 LCD display (such as this one)
• HDMI flat flexible cable (such as this one). I used D2 + A2 + 15cm cable from the link.
• 40 pin GPIO extension cable (such as this one)
• 4x M2.5x5 screws for securing the Pi to the desktop base
• 4x M2.5x5 screws for securing the desktop case to monitor base
• 3x M2.5x8 screws for securing the desktop case to desktop base
• 2x M2.5x8 screws for the monitor

Optional:

• Pi speaker expansion board (such as this one). 

All parts except the monitor connector should be printed with supports. I used eSun Bone White PLA but my options for a close matching beige were limited where I am.

OS Configuration notes:

I followed this guide by @Hypn to get the Pi to boot into DOSbox with retro splash screen.

I'm running DOSbox under Debian Bullseye (As of writing I couldn't get the custom splash screen to work under Bookworm). I used the following values in my /boot/config to get the output to fit the monitor:

overscan_left=20
overscan_right=60

After installing the LCD-show display drivers, add the following to the [all] section in /boot/config to rotate the screen to the correct orientation:

dtoverlay=tft35a:rotate=270
