A Closer Look - Outside

The Deep Silence 4 is Nanoxia's implementation of a mATX chassis, which in turn means that it is rather compact; it also looks similar to its bigger brothers when viewed from the outside. This case is still quite heavy for its size, which is a good thing as it shows that the company did not skimp on materials when creating the enclosure.


Just like with the other Deep Silence variants, the front is divided into two parts, with only the top opening up. The door swings open from left to right, revealing the drive bays and more. The unit's rear looks pretty standard, with a bottom-mounted PSU bay and all-black interior.


Both side panels are completely solid to contain internally created noise. You will find air vents on the side of the front cover, which is how fans will then pump fresh air into the chassis without directly exposing themselves as a sound-encapsulating measure.


Behind the small front door, which has sound-dampening materials padding its insides, are two 5.25" drive bays. The bays come equipped with opening clips, so you may easily remove them. There are also a reset button and two separate fan controllers here. Each of the latter can connect up to three fans for a total of six adjustable cooling units. How much these controllers can handle in terms of watts I do not know as I could not figure it out. Looking further down on the front, the bottom half is completely solid. Though Nanoxia made an effort to make the front look like aluminum, it is actually made out of plastic.


The bottom-mounted PSU bay in the rear comes equipped with two sets of mounting holes, so you are free to choose how to install a power supply within the Deep Silence 4. Above that are the four motherboard expansion slots. Each of these is protected by an individual, re-usable cover. There will always be a comparison between Nanoxia and Fractal Design cases and one difference is the lack of a vertical slot next to the four standard ones in Nanoxia's design, for example. You will find a 120 mm fan in the front; it is set to push air out the back of the chassis. Above this fan are two openings to route water-cooling tubes out the back of the chassis. You may replace these with solid grommets if you are not utilizing either.


Nanoxia placed the I/O of the Deep Silence 4 in the top of the front panel. It consists of a single USB 2.0 and two USB 3.0 connectors and the usual audio I/O. A round power button can be found in the middle. It is encircled in a ring of light acting as both a power and HDD activity LED while the system is up and running. You may install a 120 or 140 mm fan in the top panel of the chassis, but will have to remove a solid cover there that improves the Deep Silence 4's noise reduction attributes.


Tipping the chassis over reveals a dust filter on the underside of the chassis, there to protect your installed PSU from dust and grime. Two sets of mounting holes here also allow for hard drives to be installed on the floor of the chassis. Though Nanoxia mentions the 2.5" mounting holes to the left in the image above, there is no mention of the 3.5" ones to the right. You may simply remove the dust filter with the case standing up by pulling it out the back of the chassis.
