Custom Raspberry Pi 4 Build – Mini Box Server with Ice Tower Cooler, OLED Status Display and Argon One Extender Board

For a long time, I have been looking for the ideal Raspberry Pi case, however, they all seemed lacking it some way, preventing me from building one as I had liked, complete with:

• Effective cooling.
• Inclusion and space for an SSD.
• Position of peripheral ports – Ideally HDMI and USB ports at the back, with optional USB ports at the front.
• A power on / off button.
• Modern design.

With a 3D printer and some basic knowledge of 3D CAD the world is your oyster.


A shopping list, along with where to buy, URLS and price is included in the files for reference.

I’ve used an 8Gb Raspberry Pi 4, but you don’t need the 8GB version, so long as it’s the Pi 4. I’ve also used a 512GB SSD – It doesn’t need to be 512GB, but for this shopping list you need a 42mm SATA m.2 SSD (not nvme).


M.2 SATA 512GB (42mm)

USB 3 4 Port Both Side Hub

I2C 0.96-inch OLED Display SSD1306 128×64

Jumper Wires

M3 8mm Female / Female Brass Pillar Set

A4 Sheet 3mm Perspex (Grey Tinted)

Raspberry Pi 4 8GB

Ice Tower RGB Cooler

Argon ONE V2 Raspberry Pi 4 Case (you just need the boards from this)

Argon ONE Power Supply (IMPORTANT – Has slightly higher output)


USB Bridge

USB 3.0 Adapter Coupling Connector

RASPBERRY PI OS, Argon One Fan Hat Script and OLED Display

  • The Ice Tower Cooling plugs into the Argon One fan it. It has variable fan RPM for different temperatures – It requires you to run the Argon One Setup Script.

  • The OLED Display also requires various scripts to be run and python files to configure and output.

… I’ve documented these and placed in zip files of the files: OS, Argon One and Display


The top and front has perspex windows. Included in the files is a zip file: Perspex Cut which contains the templates… They’re just png images, so be sure to size them correctly.

I used a rotary tool to cut the perspex and to sand the edges.


I printed the base using PETG and the top using PLA. I used 100% infill for the best sturdiness and printed at 0.2 mm layer heights.

Supports are required, but block out the the holes for the pillars on the bottom of the base (don’t put supports here) or you’ll struggle getting the supports out and be unable to insert the pillars for the boards to screw to.

Support Parts

There are two odd looking STL files you may find. One is just a small pillar. This is to support the Argon one boards, they have too much give. There is also a sort of ‘wedge’ with a screw hole. This fits in the front left corner, to again, support the boards – You may need a slight longer screw.


There is an SLT file for the feet of the base – They designed so you glue them to the base and stick the rubber feet to it, which are provided when you purchase the Argon One case.

Please post your make – would be interested to see.
