As always, Lian Li has also focused on making this case as quiet as possible - low speed, low noise fans and vibration reduction in nearly every capacity - from the side panels to the HDD mounts themselves.Lian Li continues to innovate and excel in case design, the Lian-Li PC-A77FA Advanced Full Tower Case is another shining example!
