As you guys have been helping me in my other thread, I think Ive found out whats causing the overheating. Dell makes the case so you have to have the 2 HD back to back vertically and away from the fans. I want to remove my music only SATA HD and transfer it to an external HD case. Do they make external cases that support SATA drives? I own a Dell Dimension 4700. Thanks again for the help.
