Im looking at using 2 of these LEDs & fitting them in the bottom left hand side of my slim where the vents are. Now, I have very little knowledge of electronics, I want to use usb port 2 for the supply, im fairly certain i wont need to use resistors because the 2 leds will be wired in series, there max voltage output is 3.5 & they can operate between 25 - 100mA, which the USB port only puts out 100mA anyway. Any input for this mod would be greatly appreciated!
it would probly be better to wire them like this to get even power to both so the first one in the circut does not blow

I will agree with Nick..
Running anything parallel is the way to go when using any LED's or fan mods or anything else for that matter..
Any other way of wiring your LED's would cause one LED to be brighter as the rest down the line would dim due to power consumption on the LED before it..
