Pros: Very easy to install, looks nice in case
Cons: Coil whine is pretty bad when turned off, can hear it from the other side of my room.
Overall Review: I really liked how simple and easy it was to install as a first time builder, and it has worked great for 6 months. My only complaint is the COIL WHINE. It's pretty loud, I have my PC in my room, and I can hear it from the complete opposite side. The only way I've figured out how to make it a little quieter is to leave the few LED's on my mobo on.
