<< Here is another pic of that 235CFM beast. Yep, a fan guard would be a good idea if you were gonna buy that >>
I bought one of these babies about 2 months ago. I would get it. It moves a ton of air, but it is loud, and huge. You will either need a 400watt PS or a seperate one just to run it. It was just to big to mount in my computer case, hehe.
