From time to time I pull fan panels out of the scrap barrel at my day job. Most of them hold 2 x 4" muffin fans. There are also 3 fan panels. The 2 fan panels sit nice behind 400's and 700's.
If anybody wants one I'll ship them to a U.S. address for $10 which is the about the cost of priority mail in a padded envelope. 3 fan panels are too big for any any priority mail boxes. If interested send me a PM.
You're on your own for wiring and fan selection. Wire 2 in series so that they run slower and consequently quieter. Get fancy and use a computer fan controller with thermocouples and 12 VDC fans.
