Hi im new with this case modding (and my english is very bad too)
I was trying to make that Project Cryo but i had no Led so i started looking around and found a white led, my problem is that i dont know how many volts it needs to run.. im scared to short-circuit my mother board again. Is there anyway to calculated the led's volt?

variable power supply output 1-6 volts DC
voltmeter

turn the variable supply up untill the led lights, then measure the voltage.

White leds usually take around 3-4 volts. Calculate the resistor for 3 volts at first and see how bright the led is. Just lower the resistance from there to make the led brighter. Best indication of overvoltage is that the led starts to get warm. It should stay cool to the touch if the voltage is correct.
