Introduction, Specifications, and Pricing

Be quiet! Is not a brand I feel needs a significant introduction. While we have looked at their cases previously, they have always done rather well in our testing. The same can be said for other be quiet! products we had tested prior. Now to the namesake for the case we are checking out today. The Dark Base Pro left the TweakTown labs with high honors, nearing a perfect score which is in no way easy to pull off.


For those not familiar with the Dark Base Pro 900 Rev. 1 it is a large full-tower, even approaching super-tower based on stature alone. The Dark base pro was made for the distinguished builder who favors not just quality of materials but silence and adjustability and modularity to build a PC that was truly how you want it.

Some of the key features of the Dark Base Pro would be its modularity, adjustability, and silence focused design. One thing that many silence focused cases get wrong is that in favor of silence, they suffocate the internals which is counter-intuitive when having high-end components at the price range this chassis falls into.

The chassis we are working on today is an incremental improvement of the be quiet! Dark Base Pro 900. Aptly names the Dark Base Pro 900 Rev. 2 and it has some key upgrades which may help refresh this aging behemoth. The Dark Base Pro 900 Rev. 2 measures in at 577mm in depth, 243mm wide, and 586mm tall. With that considered I think the behemoth comment earlier is well earned in this case. The Dark Base Pro 900 tips the scales at 14.39kg or 32lb.

Motherboard fitment is listed for pretty much any forward on the market from Mini-ITX to e-ATX along with even the rare XL-ATX which we don't see much in the consumer market since the prevalence of 4 way SLI configurations have all but died off. But if you happen to have something like the EVGA X58 Classified 4-way, rest assured the Dark Base Pro 900 can fit it.

Drive support in the Dark Base Pro 900 is quite expansive with dual 5.25" slots for card readers, DVD/Blu Ray or even reservoirs depending on your build needs. The 5.25" bays can be removed, and an included fan bracket allows for further fan expansion. 3.5" drives can reach up to five with the included drive trays but can expand to a maximum of seven with purchasing a couple of extra drive trays. 2.5" drive support comes out to 10 with included trays and up to a max of 14 if opting to buy additional trays.

PSU fitment can go to a max length of 285mm while with the installation of bottom fans it would bring that down to a 150mm limit. The PSU now rests under a shroud, which is one of the enhancements that be quiet! added to the Dark Base Pro 900 Rev. 2. The PSU shroud can be broken down with various covers to support even more capabilities which we will dig into later in the review as we tear down the Dark Base Pro 900.

Cooling fitment for the Dark Base Pro 900 Rev 2 is quite expansive similar to the original version. This is because the Rev. 2 version is the same base chassis with upgrades to modernize the case with things used now expect a few years senior of the original chassis. Max CPU cooler height for air cooling will be 185mm so basically look at that as basically any cooler you could fathom should fit here.

The preinstalled fans are numbering three, with dual 140mm Silent Wings 3 model fans and a single of the same fan on the rear for exhaust. The front of the chassis can support up to four 120mm based fans or with the included 5.25" replacement bracket we can add another 140mm. The top of the chassis can support up to four 120mm fans as well and triple 140mm same as the front. The bottom of the case can support dual 120mm or 140mm while the top of the PSU shroud can support a single 120mm as well.

Radiator support is massive with sizes in the front supporting in mm: 120, 140, 240, 280, 360, and 420. Then as we move up top, we see support ranging in mm: 120, 140, 180, 240, 280, 360, and 420. Lastly, the rear supports 120or 140mm radiators. Depending on the thicknesses of radiators and installed fans, adjustment of the motherboard tray may be necessary when installing the radiator in the top. We found this out the hard way and will discuss further in the review as we reach the build.

The Dark Base Pro 900 Rev. 2 come to market at a hefty price of $269.00 so not at all for the faint of heart or those seeking budget options. The competition is stiff in this price range, especially as there are far cheaper cases that do many things very well. Cases that pose potential issues would be Lian Li's PC011, ASUS' new entry the STRIX Helios, and the aging Nanoxia Deep Silence.

Now we must push along in this review and see if enough relevant changes were made to the Dark Base Pro 900 with the Rev. 2 iteration to consider it a modern successor, and has be quiet! done enough to outfit it with the necessary options consumers demand to keep it at one of the top positions in our charts two years later.
