ATX Server Case for IKEA KALLAX

Setup

This setup consists of three main elements:

1. ATX motherboard and PCIe mount – installed at the back of the KALLAX insert.

2. Front fan intake and I/O panel – installed at the front.

3. PSU and optional SATA drives – mounted in another part of the furniture. In my setup, these are mounted directly above the PC.

Resources Required

• KALLAX Insert with 1 shelf

• M3 and M4 heat-set inserts

• M3 standoffs

• M3 screws

• M3 nuts

Building and Printing Process

Part 1 – ATX Motherboard and PCIe Mount

The ATX motherboard mount is divided into four printable parts so that it can fit on a Prusa MINI. The four sections are connected using M3 screws and nuts.

M3 heat-set inserts are used for the motherboard mounting points, allowing standard M3 motherboard standoffs to be installed securely.

The PCIe mount connects to the Quad_2 part and is designed to securely hold PCIe expansion cards. I used M4 heat-set inserts in the top mounting points.

I have successfully printed these parts in PLA. However, if you expect the system to generate a lot of heat, PETG is probably the better choice due to its higher temperature resistance.

Part 2 – Front Fan Intake and I/O

The front panels for both the fan intake and I/O can either be:

• 3D printed, or

• CNC/laser cut from a material of your choice.

Both options require the 3D-printed front mounts.

The front mounting system consists of the mounts themselves and an optional connector piece. Both use M3 heat-set inserts. You can choose whether to use the connector piece or install the mounts individually.

3D Printing the Panels

Download the panel files and print them in PLA or PETG using your preferred settings.

I have not personally tested the 3D-printed versions of the panels, but since they are large and flat, I recommend using a brim to help prevent warping.

CNC / Laser Cutting the Panels

I cut my front panels using a home CNC router with a single-flute bit.

For cutting plastic, I recommend using a single-flute bit. CNC machines vary significantly, so test your feeds, speeds, and toolpath on a spare piece of material before cutting the final panels.

I have also uploaded the .nc file that I used on my own machine. Please check the toolpath, dimensions, zero position, feeds, speeds, and compatibility with your CNC controller before running it. Do not assume the file will work unchanged on another machine.

Alternatively, download the panel files and the A3 layout sheet and use them to create your own cutting paths in your preferred CAM software.

Part 3 – PSU and SATA Mount

This is the only part of the project that I did not design myself.

Instead of re-uploading someone else's work, I have provided links to the relevant models. Please refer to the original creators' instructions for printing and installation.
