    I'm thinking about getting some case fans in addition to the ones already on my computer....how would I get power to them (what cords would I connect) and how hard is thius?

    You should only need 1 or 2 case fans if you're not overclocking anything. If you are overclocking, check some overclocking web sites for diagrams regarding airflow. You'll want some fans pulling air (usually in front) and some fans pushing air (in rear). Some fans need to attach to mobo for power, others use the power connectors from the power supply. Even others take a connector from PS, and extend another connector off of it. You'll want to make sure you've got a big enough power supply to run all these fans. Check the overclocking websites, they can go into more detail.

    any fan you buy should come with a 3 pin (connects to motherboard) to 4 pin (connects to powersupply) connector, use it!

    Some fans use so much power that they can blow the MoBos fan header.
