Need help with LEDs (Wiring)

[Slurpee12]

Hello everyone

I recently found this guide -> http://forums.overclockers.co.uk/showthread.php?t=18172810
and I became interested in it. Right now, my case doesn't have very much lighting so I thought I would give a go on cosmetics, for a little side project.

That guide uses 16 LEDs. I think that that will be too much, so I'm planning on just using 4 for now. However, I've run into some trouble. I'm a bit lost on how the wiring is done.

WIll I have to use 1 resistor for each LED or can I use one resistor for all four LEDs?
If that is possible (it's also ideal), how would I go about wiring it? Could I solder a positive wire to the anode of the resistor then to the anodes of the four LEDs; then solder a ground wire to the cathode of the resistor then to the cathodes of the four LEDs? Then, I would solder respective wires to the cathode and anode wires from the resistors to a molex for power. Does this sound correct?

According to the link you've provided the OP of that thread was kind enough to pass this on as well

OP has used 1 resistor for every 4 LED's

Diagram above and the thread you've linked has some nice details to work out. Also you should have your LED's in series and not in parallel(if that's what you're thinking of doing).
