At the back of H440 there are a series of eight PCI expansion slot covers – each have the ventilation cut-outs and make use of a thumbscrew for easy removal. To the immediate left there are two circular rubber grommets.


Above these covers there is a 140mm rear exhaust cooling fan; this fan is an FN V2. At the top of H440, although there is no perforated mesh gracing the roof, there is a bracket which can accommodate two 140mm fans or three 120mm fans. This also paves the way for different sized radiators to be housed in this top section.


For storage there are five designated HDD trays which are accessed from the reverse side. Each of these trays can house 2.5” and 3.5” drives and feature two thumbscrews for easy removal. 3.5" drives can be attached to the top-side while 2.5" drives can be attached to the underside of each tray. The useful thing about this design is that redundant trays can be detached from the chassis to enhance airflow and extend the graphics card clearance.
