My issue is with the case, it has 5 fans included and I would like to be able to run them all, and I was wondering how I could use the existing three pin fan connector, or the PSU to rig four more fans.
It's great that you are adding more fans! 'Daisy chain' all the connectors together and then connect the cable to the PSU. All fans connecting in this manner will run at full rated speed. Look into DbA ratings before buying the fans.
Mine is a Scythe and I recall paying less than $20 for it. I must say that it dresses up the computer rather well. And now there are 'touch control' fan controllers with digital outputs that look real high tech -
