LED matrix for Cooler Master Qube 540 case

Add a big RGB LED matrix display to your Qube 540 case. I had two requirements for this design:

• It had to integrate with the Qube 540 design, meaning that we see the same kind of ~14mm holes spaced 20mm apart.

• It still needed to allow good air flow through the case faces.

There is a base grid onto which the WS2812 LEDs are put (see photo). This would attach to the case with 6x2mm magnets. The LEDs are arranged in a row-by-row serpentine pattern in my case. If you can find a strip where the LEDs are spaced 20mm apart, wiring would be much simpler. Then there is a cover that mainly hides most of the wiring. The cover is spaced by pegs so that there is plenty of airflow. The pegs held the cover to the main matrix grid with friction in my case, but you can add a couple dabs of super glue if necessary. Lastly, there is a grid frame to make it a bit prettier. (In some pictures, there is another grid in the back -- that is only for reference of how it would look wrt the case.

If you want to cover a bigger area, it is very simple to tile these and extend them.

I used an Arduino Nano to control this. The Arduino can be put into one of many cases readily available on Printables and hidden inside the case. Also, depending on your power supply, you can power this directly from your PSU's 5V line. (As shown, this will pull at most 3.24A = 60mA*54, or 16.2W. So not that much.)

Code for a few RGB animations are included. (The one pictured above is the 2d bounce animation.) One possible future application might be using the Arduino to measure fan speeds or temperatures and show them as bar charts or to have them control parameters of the animation.

Used the original case design to verity dimensions and fit (in CAD so far, since I do not own the case).
