Product review (4 stars): Air-suction port is off to the left side.  Why not in the middle?
The metal housing is ok (not as thick as the one I'm replacing).  There's only 1 fan, which is off to the left side, and there's nothing on the right side (yet still requires a filter on the right side just for the look).

Fan speeds #1 & #2 are quiet.  But #3 is a little noisy, and the Boost speed is not what I would want to use everyday.

I can't give this thing a 5 star due to the way they put the fan (off to just the left side).
