be quiet! Dark Base 700

Visual inspection

The be quiet! Dark Base 700 has a good design, with linear brushed textures applied on the front and top panels. The case also has RGB integration around the front and a tempered glass side panel. In addition, the Dark Base 700 is designed to offer a good airflow and a low noise output.
The Dark Base 700 is available in two different colors: Black and White. The case has a weight of 13 kg, with the dimensions: L x W x H: 544 x 241 x 519mm.


The main side panel is manufactured out of tempered glass and has its edges blacked out with a matte coating. The glass surface has a dark tint that will cover most of the interior of the case, and will highlight the illumination inside. Unfortunately, this dark tint will also create a highly reflective surface on the panel, which means that if the case is too close to an RGB peripherical, it will also reflect that.


The tempered glass side panel is attached to the case by four metallic thumb screws. The glass panel itself sits on rubber grommets which are attached to the chassis. This system is outdated and does not provide any security in handling the glass panel, especially when aligning the cutouts in the glass with the standoffs. A swivel mechanism would have been better, especially since the glass can be chipped or broken.


The other side panel of the case is made from metal and has a notch style mounting system. The panel itself is attached to the case with the help of two captive thumb screws located at the back. In addition, this panel has a soft foam pad applied on its inner side to help reduce the noise output of the case.

The front of the case is made out of plastic and features a linear brushed texture across its entire height, in addition, the be quiet! logo is placed on the lower side.


The front plate is the only item that is removable on this side of the case. The removal process is simple, as you are really just prying the panel off the case. Unfortunately, here plastic clips are used which can break. A hinge mechanism would have been a much better choice. Behind the front plate, there is the main intake dust filter which is attached to the chassis by a plastic clip at the top.


The RGB system uses a 3 contact PCB design, this is done so that the wire usage is kept to a minimum. In addition, the front plate can be removed without interfering with any cables, the connection is instead achieved through two PCBs touching their contact pins.


The intake of the case is done through the sides of the front panel. These gaps are not large enough to allow for a good airflow of the number of fans which can be installed on the front of the case. Speaking of which, at the front, the Dark Base 700 can accommodate either three 120mm fans or three 140mm fans. The supported radiators at the front of the case are: 120, 140, 240, 280, 360 mm. In addition, on the front of the case, a single 140mm fan is preinstalled, this fan is part of the be quiet! Silent Wings 3 series.


The I/O panel of the Dark Base 700 is placed above the front panel of the case. Here the following buttons and switches can be found:

– 1x Microphone
– 1x USB 3.1 Gen 2 Type C
– 2x USB 3.0
– 2x USB 2.0
– 1x Fan controller

The back side of the case is simple, with a standard layout and no added features. At the top, the exhaust vents of the top panel are exposed. This is the only area where the exhausted air of the top mounted fans can exist the system.
The case has a total of seven expansion slots, with their covers held in place by thumb screws. In addition, a two slot vertical graphics card mount is available on the right side.


The underside of the Dark Base 700 is covered by a removable mesh dust filter. The filter is removable from the front of the case, and only if the front plate is removed.


The case has four plastic feet; these have a wide shape with a metallic mesh applied on the sides. The contact between the feet and the surface where the PC stands on is done through rubber pads.


The top of the Dark Base 700 is almost completely closed off. The only vents for exhausting the air inside the system are placed on the back edge of the top panel and on its backside.


The interior of the Dark Base 700 is similar with that used on the Dark Base 900. The main feature of the interior and the structure of the case is that it is completely modular. Instead of rivets, be quiet! used phillips screws which are removable. This means that the Dark Base 700 can be converted from a standard layout to an inverted layout.


The lower part of the interior is covered by a shroud that is removable. In fact, the shroud is composed out of a total of five plastic made panels. Four of the panels are on the top while the fifth is covering the entire side of the shroud. With the panels removed, a fan can be installed on the top of the shroud.


The back side of the interior has approximately 26mm of space between the motherboard tray and the side panel. There are plenty of tie-down points for cable management around the back of the motherboard tray.


On the upper left side of the case, towards the front, there are a total of five plastic covers that can be removed. Here a regular storage cage can be installed which will increase the storage capacity of the case and its position.


At the front of the case, and on the lower part, there is a dedicated HDD cage. Here a total of two 3.5” storage devices can be installed, or four 2.5” SSDs. The cages can also be removed and reinstalled on the upper section of the case.


Behind the motherboard tray there are two storage trays installed, which can accommodate a total of three 2.5” storage drives.


The Dark Base 700 has an integrated fan hub and fan controller. The fan hub is installed on the back of the motherboard tray. The hub as a total of six 4 pin fan headers and multiple RGB headers. In addition, installed on the PCB there are two switches for controlling the speed mode for the connected fans.


The top side of the case features a sliding metal plate which will hold both radiators and fans. This is the only way to install the fans or radiators at the top of the case, as the top of the chassis is covered by a solid panel. The installation process is made easy thanks to the sliding mechanism and the mounting spaces offered.


The cables of the I/O panel are long and completely black.
