thanx rdagger for the reply, not sure what yu mean by run the leds in parallel??.....
Toonces:
To run the LEDs in parallel you wire the +12V to each LED's positive leg and ground to each LED's negative leg. Series wiring would be the leg of one LED connecting to the leg of the next LED. More than likely the resistors you received are for 12V operation. Yes, it could be 5V but most vendors sell them for auto applications at 12V. If you can post the value of the resistors I can tell you the most likely voltage. To find the value, compare your resistors to the chart here http://www.elexp.com/t_resist.htm  you can also try the resistor calculator here http://www.webcalc.net/calc/0231.php

If the resistors are 470 Ohms or 580 Ohms (or somewhere around that), then most likely voltage is 12V. If they are around 100 Ohms then it would be 5V.

Hope that helps,

In addition to all of the great information offered to you, you may also want to consider purchasing a splitter to plug into the power supply in your computer.  This way you still have a proper connector in your computer that can be quickly reverted to what it was intended for.  Then just hack into one of the lines on the splitter (pigtail).

Way ahead of you.  Already hacked a pigtail out of a junk case so I wouldn't have to destroy a lead coming off my PC power supply.  Great idea though!
