AeroCool follows the philosophy that “less is more” in its VS-9, using less metal to provide more ventilation. Most of the top and base are open to airflow, along with 1/3 of the left side panel and all nine 5.25” bay covers.
Though the VS-9 could support up to eight fans, the rear panel holds its only included fan. Rubber grommets under it protect the hoses of external water cooling systems, while folding side panel handles found even farther down can be left unfolded to ease access to rear-panel ports.
The VS-9 top panel can hold fans of multiple sizes, thanks to its continuous series of holes. The upper limit is two 140 mm fans, though the heat pipes and DIMM latch locations of some motherboards will prevent such large coolers from fitting.
The “front panel” port section is located along the VS-9’s left-side edge, and its ports are oriented for the top of a USB flash drive to face right.
Open-cell foam behind the drive bay covers prevents a see-through effect, while still allowing good system ventilation.
