The AeroCool S9 Pro case was designed to hold one of the largest case fans a lot of people have ever seen. A 40CM covers the entire right side panel. Running at 400 RPM it outputs about 250CFM of airflow over entire innards of the case. This case also features 9 useable 5.25″ drive bays, one of which has a 3.5″ converter. All 9 bays are covered with wire mesh to provide optimal airflow throughout the case.
Taking a closer look at the front panel doesn’t really reveal a whole lot. This black sand-blasted finish and reserved design gives it an elegant style. The 5.25″ bay converted into a 3.5″ bay is along the upper most drive bay which also has a wire mesh cut out for the 3.5″ hole which can be later removed if need be. Small white text along the top of the bezel shows the case name, S9.
A small white AeroCool logo centers the lowest drive bay. The external connectors are found along the top of the case and are not part of the bezel. There power and reset buttons protrude from the case slightly while the two USB, audio connectors and eSATA connections are flat along the case. I am surprised to find that there also isn’t any power or HDD activity LED’s on this case.
The large 40CM covers the entire right side panel, protruding from it by about half an inch. This large white fan is covered by a plastic circular cover. The white fan gives the case a bit of contrast to the basic black design. Two standard sized thump screws hold the side panel to the case.
An additional latch along the center of the back of the side panel holds the side panel to the case. It also makes the side panel easier to remove once the screws are off because all you have to do is lift up and pull backward on the latch to remove the panel. Also along the back there is the typical setup for a back of a case: power supply slot, I/O slot, expansion slot covers, fan grill built into the case which actually doesn’t come with a rear case fan and an extra grill next to the expansion slots for optimal airflow.
