Summary: Bought this to replace the one in my Twelve-Hundred V3 case, didn't realize that this replacement doesn't have the blue LEDs of the original. Don't really care because I turn off all the LEDs, but it's kind of annoying because the switch doesn't sit snugly in the case, since the case hole was meant...
Summary: When it cooperates, this fan is great -- I can't speak for other cases but it snaps right in to the Antec 900 and moves a ton of air. Be ready for a little frustration in removing the top panel to replace the old one. However, I bought a replacement due to my original fan rattling at all speeds.
Summary: The fan fits my Antec 900 two case perfectly. He only draw back is that it doesn't seem to move as much air as the stock LED big boy. My only wish is that manufacturers would have OEM parts available for consumer purchase.
Summary: Great direct replacement for my Antec case. Pretty quiet on the lowest setting and it moves a lot of air. Not sure why you would ever need more than the lowest setting so it seems like a waste to have the other two.
The fan arrived quickly and was a perfect replacement for my fan

Summary: The fan arrived quickly and was a perfect replacement for my fan. My original fan died on me after three years. I have an ANTEC 900 case. Physically replacing it was a great pain. My computer is running smoothly and quietly again thanks to this replacement.
Summary: I had to replace my existing fan due to the bearing going out (wobbling). Found an exact replacement to install this top fan on my Antec 902 series mid tower case. After figuring out how to remove my top cover case, I had no problem installing the Big Boy 200.
