Refer to my other articles on adding, upgading or removing just about any piece of hardware.First things first, get that case off your PC. This is usually done by removing the screws on the back. Don't remove the ones near your power supply! This will cause your power supply to fall out. Simply remove the screws along the side that seem to be holding the case to the frame.
