Summary: I am glad I picked this fan up, and it does it's job, but I must say with my Antec case this top fan was the most frustrating thing in the world to install. Installation took about 45 minutes. This just should not be.
Summary: My installation is a departure from most applications. I wanted to convert a glass china cabinet into a multiple use AV equipment and display case. Since it wouldn't have served my purpose to leave the cabinet door open, I resorted to modifying it to provide adequate ventilation so as to avoid overheating of my sensitive electronic equipment, which throws off a good deal of heat.
Summary: Short but sweet, this fan is an excellent replacement for the original Antec 900 "Big Boy" case fan. I used brute strength to peel the case apart, and it was an easy install and runs quietly while cooling my components! Top notch! Fits perfectly as well!
