Raspberry Pi 4 case - Retro tower desktop

A retro style beige Raspberry Pi 4 tower case. It has a working power button, LED, and IO activity LED. The SD/microSD card can be inserted like a floppy disk to swap between different operating systems. It also has 2 HDMI ports, audio jack, and USB-C power on the rear of the case.

There is space for a 40mm exhaust fan and a 40mm or 50mm front intake fan. There is also enough space for a large cooler like the ICE tower.

I also made a Raspberry PI 5 version of the case. https://www.thingiverse.com/thing:6572558

NOTE:

There is now a slightly improved V2 of the case.

Changes:

Added version of case that is 1.5cm taller

Increased hole size for push button

Added hex cutout to use the included nut for a push button

Moved wall ridges to prevent interference with tall connections on GPIO

V2 cases still use the original side and front panel unless there was a size change

Parts needed (links at the end):

Micro SD to SD Card extender: 1

Micro HDMI to HDMI Adapter Cable: 2

Panel-Mount USB-C Extention Cable: 1

40mm 5V fan (for exhaust): 1

Low-Profile CPU Cooler or ICE Tower Cooler: 1

SPST Momentary Mini Push Button: 1

5mm LED with resistor: 1

3mm LED with resistor: 1

#6-32 UNC thumbscrew (standard PC case screw): 2

#6-32 UNC screw or M3 screw (standard PC case screw): 6

various wire/header connectors (for connecting fans/LEDs/power button)

Optional:

Front 5V 40mm/50mm fan: 1 (note: I've not needed this even when overclocking the Raspberry Pi)

Noctua NF-A4x10 to replace CPU Cooler fan: 1

Panel-Mount 3.5mm AUX Male to Female Extension Cable: 1 (note: pre-made cables may be too long and should be shortened.)

Assembly instructions

Prepare all parts

note: any places that require screwing plastic parts together can be replaced with glue if you are way too confident/lazy.

- Print out all parts with whatever material/color you would like. - (optional but helpful) Use a thread tap on all screw holes Start Assembly

- Tap threads for push button. If you don't have a tap, you can use the push button to create the threads. You may need to use a file to help make sure the push button fits if you don't have a tap. - Press fit 3mm LED into the main case. Glue can be added, but the press fit should hold it fine. - Press fit 5mm LED into the main case. Glue can be added, but shouldn't be needed. - Put SD card extender in the SD card tray and attach to the case with screws or glue. This may require a long screw driver that can reach through the fan grill or a very short one that will fit in the case. This is easer to do before anything else is in the way. - (Optional) Attach front fan with screws - Screw/Glue in front panel. Make sure LEDs are visible and the push button does not get stuck. - Put HDMI adaptors in the HDMI holder, but don't mount it in the case. Connect wires to the GPIO Header

- (Optional) Make a simple splitter for the CPU/Case fan(s). I have the fans connected to 3.3V (pin 1) and ground (pin 9). The fans can use a 3.3V or 5V pin for power and any unused ground. - The push button goes across pin5/pin6 (polarity doesn't matter). - The power LED goes to pin8(+) and pin14(-). - The GPIO LED goes to pin37(+) and pin39(-). - Connect all wires, connectors, and micro SD card extender to the raspberry pi before carefully placing it in the case. At this point all cables/extenders should be connected to the Raspberry pi, but not the case. (note: if using the ICE or low profile heatsinks, they should not be attached at this point) Finish Assembly

- Use the brass spacers/mounts/standoffs from the cooler to screw the Raspberry PI to the case. These 4 brass pieces should now be going through the Raspberry Pi's mount points into the case. - Add thermal paste or the thermal pad to the processor and attach the CPU cooler with the included screws. - Screw in the HDMI Holder. - Screw in the USB-C extender - Screw in the Audio jack - Attach the rear exhaust fan. - Slide the side panel on and add thumb screws config.txt setting

- (Optional over clock setting -- Use at your own risk) overclock
