Product review (5 stars): DIY-ing is a part of the joy of homebrewing
Could I have built something cheaper?  Of course.  In fact, I did, with a computer fan and misc. things I had lying around.  This moves much more air and keeps my tower much cooler.  Yes, DIY-ing is a part of the joy of homebrewing, but if you're at the point where you don't mind having someone else make one of your toys, I definitely recommend this tower cooler.
