Hi, I am thinking of making some sort of light thing for my mums birthday present. I dont know much about LED's. I was thinking about buying them from maplins (im UK ). These were the ones I was going to pick:

Not sure what colour yet. Could someone tell me how to run 8 of these LED's off of an old 230Watt pc power supply I have lying around. I know how to short the power supply so it will work without the pc (gonna put a switch there too).
The specifications for the LED's are further down the page on the link above. Im guessing that I have 2 lots of 4 in series. Also, Im guessing that I would need a resistor, but I dont know the resistance I need.
This is a 2d export from sketchup:
I was thinkging of putting the power supply in the bottom part, and also including a draw or a small cupboard there too. The top is going to be made from plexi that I am going to frost
I just need to know about the LEDs (the resistor I need, and how to wire them up).
I should be modding a tower as soon as I have one come in!
