A Closer Look - Inside

Simply remove the two thumbscrews holding each side panel in place to access the interior. Nanoxia lines the interior of each side panel with fairly thin sound dampening materials to aid in keeping noise down. At first look, one can see two hard-drive cages and an all-black interior. A large opening in the motherboard tray should allow for easy access to the CPU cooler's underside, while various grommets along the board's edges will come in handy when it comes time to keep things clean within the case, though they may be a bit small.


There is around 18 mm of space behind the motherboard tray, which is further reduced by the sound dampening material on the side panel. While 15 mm can be used to route cables, you will need to invest a bit of thought and time into the process to avoid not being able to close the case up afterward.


The Deep Silence 4 comes equipped with six 3.5" metal hard-drive trays which may also hold 2.5" units. These trays have been placed in three cages, two of which may be removed by pushing down on clips on the opposite side. Once removed, you should have plenty of space for even the biggest GPUs out there. As you can see, there is a green-bladed 120 mm fan to push cool air into the chassis. It is either used to cool hard drives or create beneficial airflow for installed expansion cards.


Above the hard-drive bays are two 5.25" drive bays. Each is equipped with a pair of spring-loaded locking mechanisms. While these do hold alright, screws will still be the best choice here.


The PSU bay in the bottom of the rear is lined with foam as an anti-vibration measure, while foam pads on the floor also act as vibration barriers. Above that are the aforementioned expansion slots, with each individual cover held in place by a thumbscrew. You will find the exhaust fan in the very top—it is of the same type as the one in the front; both units come with sleeved cables and 3-pin connectors.


Taking a quick peek at the floor of the Deep Silence 4, there is the 2.5" mounting possibility. Nanoxia having chosen to offer this extra instead of a fan-placement possibility is pretty nice. In the ceiling of the chassis, you can clearly see the cover for the air vent and some sound dampening padding to the right of it.


To keep with the looks of the chassis, all cables within the case are sleeved. The connectors for case functionality and those to route I/O out to the top of the Deep Silence 4 are of the default variety, so you should have no issue plugging those into a modern board. I do miss a USB 3.0 to 2.0 connection possibility, though. Instead of a CPU power cable, Nanoxia could have included such an adapter as it would have been of more use. You will also find a Molex plug and six fan connectors within the case. The former is used to feed power to the latter. Each plug is labeled, so you know which fan to connect to which controller. The Deep Silence 4 can, interestingly enough, only hold up to three fans, although there are six connectors.
