Inside the Dark Base Pro 900 Rev. 2

Here we wanted to show you the front panel with the door open and filter removed so you could see how much access you get when cleaning and maintaining your rig from the front. If you wanted to go deeper, you could disengage a long string of clips to remove the entire panel, but it's not necessary as removal of the filter gives you the lion's share of what you would need to clean. Do note that the front panel door has sound deadening to help absorb noise before it can make it out to your serene environment.

When pulling the glass panel, we can see that be quiet! strapped in the two accessory boxes well with twist ties. The larger box in the 5.25" bay holds a bulk of the accessories while the thinner and longer box hold the hard PCB LED strips. The internal of the chassis has been cleaned up a lot as the original Dark Base Pro 900 had seven drive caddies jutting into the main chassis taking up space that may not have been needed by most builds.

Instead, the Rev. 2 employs covers here, and trays can be added as required. This gives a much cleaner and open feel, and add to this the integrated PSU cover which is removable with four screws. Overall first impressions, the Rev. 2 has done some maturing over the past two years and come back looking like a more modern part while carrying the same popular design.

Up front, we find the two preinstalled 140mm silent wings 3 fans which are improved over the original. The original Dark Base Pro 900 offered silent wings fans which topped out at 1000RPM, while the Rev. 2 model offers up to 1600RPM for more performance when needed.

Up top, we can see the 5.25" bays which can be removed and an included adapter can be installed to install more fans higher up. There is also a mounting plate for reservoir or pumps that can be used in conjunction with an HDD cage to enable custom liquid cooling parts mounting. Up front here we can install a vast array of radiators up to 360 or even 420mm should we opt for 140mm based cooling.

The top comes off rather quickly as soon as we find all of the tabs and press them in succession to release the panel. When removing you will notice the qi charger stays in place and the front panel I/O you can now see in its bare state mounted to the chassis. The top allows for mounting of similar radiators as the front except for the addition of a 180mm based option for a single massive fan, although except for Phobya I have not seen many radiators that size. All fan mounting is slotted to allow more precise component fitment to match your needs.

Looking at the motherboard tray area, we can see that with accessory boxes removed, the area is a vast expanse of possibility. To the far right, we see the HDD tray covers that stay in place until needing to be removed so that an HDD tray can be added.

The motherboard support is from ITX as mentioned before up to E-ATX or even XL-ATX, which is why we have eight expansion slot openings. There are three central grommeted cable management holes along with large open areas around the top and bottom to allow easy cable management. The CPU backplate hole is enormous and should allow easy access to any backplate without issues.

One thing that's of particular note is to the left on the frame we can see three screws with orange rubber washers. These are surrounded by other holes, and while it may be confusing as to their purpose, this is to allow the motherboard tray which is fully removable to be inverted and also height adjusted should you need a large top mount radiator.

This vertical movement allows for fitment of various parts without causing interference with the motherboard or installed components. Default, as you see here, has 40mm of clearance which anyone who knows AIO's knows this will be an issue, something we were not aware of at the time. Moving one of the small panels above the PSU mounting area to the top lowers the motherboard and allows the space to expand to 62mm. Moving both plates to the top can offer up to 84mm of space, which means all but the thickest radiators would fit without issues.

The PSU shroud is a significant aesthetic addition to the Rev. 2 model as the original had the PSU out in the open. The PSU shroud is all metal with removable plastic covers on the top. THE PSU shroud has a stamped be quiet! logo which does not stand out but is visible enough without it being annoying.

As we see here, the PSU shroud does not reach all the way back, instead, offering a decent gap to allow cables to pass through without needing defined holes which may not match precisely with the system configuration. There are multiple separate plates in place which can be removed, and we will look at that next.

Here we removed the PSU shroud and its covers to show what can be done. The large center cutout can use an included bracket to mount an SSD should you want to showcase a particularly good looking or even RGB SSD. Here. There are also fan mounting on the PSU shroud, and as you can see, each panel can be removed independently based on the build needs. For example, the front hook-shaped piece can be removed to fit a thicker radiator in the front of the chassis while retaining the PSU shroud.
