PowerMac 9600 owners
Don't know if anyone knows this. Just wanna get it out to the community so others can do this if they want... On your PowerMac 9600, there's a hidden place to put a fan. It's right behind the speaker (that transparent green box that supplies power to the door fan). There are two holes to a 9cm fan to be mounted on to it from the other side of the metal case, not inside of the green box. You have to removed the speaker from that box and drill some holes to allow air flow. I really think that this was goin to be a fan, until they thought of the fan on the door idea.
