There are two places to mount fans directly to the chassis itself.  A fan mounted on the front oft he chassis is normally considered an intake fan. Oddly enough, Sunbeam did not install an intake fan. So that leaves us to do the legwork.

     It's a simple matter of unsnapping the face plate and removing the 3.5" drive bay. The instructions are even in the manual for the enclosure on how to do this. Since good ventilation is a must, we'll go ahead and install one for good measure.

     The Double Core-Fan rail is meant to be a tool to help increase ventilation within the enclosure itself. By using low speed fans at the intake and exhaust positions you can reduce a lot of noise outside the enclosure. However, low speed fans also do not move the highest volume of air, so Sunbeam has come up with this as an alternative. It's usefulness is going to depend most on the type of system you intend to build, as we'll see in a moment....

     The last avenue for ventilation is on the side panel. While the bottom air grille is for passive air movement, the top grille is intended to be used with either an 80mm or 120mm fan. The fan will remain inside the enclosure. To add a slight accent to the enclosure, Sunbeam has installed a low speed blue LED fan.
