well you would need a driver, particularly one that converts the power supplies 12v rail to something around 3v. radioshack sells all the parts you would need to make a driver.
if nothing else, you could put a simple resistor in succession to the LED's, one that would limit the current to the LED to about 20mA.
ohms law. start reading.
there is no point useless your gonna do a lot of electrical or electronic work, you will just bore yourself.
if you want to do something with no real clue of what you are doing, i suppose you could skip the ohms law bit. for those of us that like to be well educated i would suggest reading into it. if you are going to do something, you might as well put 100% into it
i have an NVQ 2 in electrical, i think i know what im talking about,
lol.... that's... cute. i read a 300 word article on aeronautical engineering once... brb gonna go build a 747.
i have an NVQ 2 in electrical, i think i know what im talking about, it does help to know ohms law but you dont need to know it fully to connect a led to a psu. they are not asking about 3 phase load balancing, so there aint no point.

If you want you computer to have colours, don't use LED's. Use Xmas lights, they are way way cheaper and have more colours
