Fan assembly

I am a very novice computer user but has nonetheless thrown me into such a project. However, I have got a little problem in my new Chief Cabinet Tech, there is room for 2 extra 80 mm fans in front and one 120mm rear fan, but my ASUS A8v deluxe motherboard, there is apparently only one connector for fans. How you get connected to 3 extra fans to only 1 plug?

Draw power from the 12V power supply connector, you need some small plug-converters (and cross your fingers that you get them in decent quality - I have had some ever just dropped by).

How can I draw 12v power from the PSU? What equipment will be needed for this? Also, where can I get those plug converters that you have mentioned.
