## Parts list

The parts list will include everything needed if you 3D print the case.

## Parts you probably have

- Soldering kit
- Cables
- Jumper cables

## Locating the f-panel and checking the pin layout

The f-panel is usually located on the bottom right of your motherboard. Pin layouts can vary here so be cautious and check which pins are where. Here is an exanple of the Z270X Gaming 9:

The only relevant pins for this build are:
- Power LED +
- Power LED -
- Power Switch +
- Power Switch -

# Building

## Preparing the case

First of all you need to place the component into the faceplate. The toggle switches are keyed and have a specific orientation so they can sit flush. The button needs a bit of force to but into place, alternatively you can also screw it in. Once its done it should look something like this:

Then the heated inserts need to be melted into the holes of the case. [Here](https://www.youtube.com/shorts/C2rznl1uIuc) is a random video I found which shows the procedure of doing it. Make sure that the inserts are straight and flush. The end result should look like this:

## Preparing the wires

Get a rough estimate on how long the wires need to be from the place you want to put the box in and your motherboards f-panel. Leave some extra wire just in case, it's better to have a bit more than less. On one of the ends you need to solder in a female jumper cable so you can slide them into the connectors of the f-panel.

## Wiring

The wiring will be inverted vertically since this you will look at the faceplate from behind. I recommend color coding the Power LED+ and Power LED- since you will otherwise burn out the LED of your switch. As for the power switch the polarity doesn't matter.

I used:
- blue: Power Switch
- red: Power LED +
- white: Power LED -

And here is how it should look like IRL:

## Routing the wires

To route the wires I removed one of these gpu placeholder slots so I had enough space.

And here is how the wires look like when they are connected to the f-panel (sorry for the quality it's really hard to get a good picture since it's pretty cramped)

# Expected behaviour

Now everything needs to be screwed together and is ready to test.

The left toggle switch wired in series with the button, so the button will only work if it is turned on. The right toggle switch turns on and off the LED of the button. This is just in case you get disturbed by the light you can turn it off (maybe when watching a movie?).
