I did this because I did not like the red LED color and I did not want to have to change the color every time I turned on the PC.

*****************************************************
There is an IC marked U11 and three resistors (0 Ohms) marked R54, R55 and R56 beside it on the printed circuit board.
Every time you press the button, the IC sets the voltage on one of the resistors to 0 and the other two to 5V. That turns on one of the LED colors. When you turn all the colors off, the IC sets all three resistor voltages to 5V.
When R54 is set to 0V, the red LED is on. When R55 is set to 0V, the green LED is on. When R56 is set to 0V, the blue LED is on.
Let's say that R54 is between 54a and 54b, R55 is between 55a and 55b, and R56 is between 56a and 56b, as shown below.
54a--------R54--------54b
55a--------R55--------55b
56a--------R56--------56b
It boots up red as is.
Green boot-up
****************
Remove R54 and R55.
Connect 54a to 55b. Connect 55a to 54b.
Blue boot-up
*****************
Remove R54 and R56.
Connect 54a to 56b. Connect 56a to 54b.
