RELOCATABLE MOTHERBOARD TRAY
Flexibility for individual requirements
The decoupled motherboard tray adapts to suit individual requirements, being completely relocatable and usable as a test bench. You can adjust it to three different heights or install it alongside the left panel in an inverted layout with redefined airflow. It is fully compatible with E-ATX and XL-ATX motherboards.

SILENT WINGS 3
Impeccable cooling and silence
The three preinstalled Silent Wings 3 140mm PWM fans offer virtually inaudible operation. They are equipped with a smooth-running 6-pole motor, durable fluid-dynamic bearing and airflow-optimized fan blade design. The frame has funnel-shaped air inlets that generate high air pressure.


MODULAR HDD SLOTS
Generous space for your setups
The installation options are flexible thanks to repositionable single HDD slots. Supports up to 5 HDDs, 10 SSDs and 2 optical drives out of the box. The practical slot covers serve to hide any unused HDD slots and keep the inner workings neat and tidy. This enables you to create systems that are just as individual as you are yourself.

VERY FUNCTIONAL PSU SHROUD
Offering unexpected possibilities
The PSU shroud offers you a variety of solutions – not just for hiding the PSU and to keep the system neat and tidy. The cover plates are separately detachable, making it possible to install a fan or an SSD on the top of the PSU shroud and leave enough space for a radiator in the front.

FULL CIRCUIT AIRFLOW SYSTEM
A silence concept by the silence experts
With its smart silence concept, Dark Base Pro 900 rev. 2 is the perfect case for the extreme requirements of overclocked systems and super silent water-cooled PCs. It can carry up to seven additional fans, up to four radiators and has noise-reducing vents all around the case that provide ultra-effective full circuit airflow.


DUAL RAIL FAN CONTROLLER
Creating separate cooling zones
The eight PWM fan connectors are divided over two rails, and each is switchable between Silence and Performance Mode. This makes it possible to create two cooling zones that can be controlled by just the front panel switch. If you want all fans to run at the same speed, you can switch both channels to the same mode.

TEMPERED GLASS AND LEDs
A perfect view inside your PC
The case is equipped with an elegant, fully windowed side panel that is made of tinted and tempered glass. The eye-catching internal LED illumination comes in six switchable colors. You can locate the LED strips freely inside the PC case.

SMART I/O PORT AND CONVENIENT CHARGER
Fulfilling practically every desire
The front I/O port offers perfect compatibility for your high-end PC. A connector of USB 3.1 Type C Gen. 2 is supported. Integrated wireless charger for Qi enabled devices such as smart phones.
Pros: I'm reviewing a little early. The rest of my components won't be in for a couple days but I had some minor anxiety about the case based on recurring review themes. However, I've spent some time playing with it, pulling the various components out and plopping them back in, etc, and I'm a little annoyed at the fussing. = Legit Yay-points that are likely to grow as I build this thing out with no big negatives assuming no electrical shenanigans: * They've been taking notes. Lots of minor old complaints addressed. * My first case (corsair carbide 400R) was an excellent mid-tower for cable management and ease of assembly. This one is mostly better in that regard from what I'm seeing. * No quality complaints so far. If people weren't just reaching, be quiet! has attended to any/all things I was looking out for based on fairly old negative reviews. * Build quality is very solid. * Unholy doo-doo-butter (this was once a much simpler non-expletive) can you stuff a lot of parts and then even more super-quiet fans if you need the cooling into this thing. If my review convinces you, wait about 3 days from the publish date, just in case I try to build and faceplant on all manner of bovine sacroth.
Cons: = Now for the Unreasonable Complaints of Other Reviewers section * Thumb screws are too tight and there's stripping! - Some were a little tight. Applying gentle pressure with a Phillips head to the phillips head slot on the occasional over-tightened thumbscrew resulted in no jolting or grinding. It just unscrewed with just a touch more torque than I could achieve with my thumb and forefinger alone. The screws and rubber washer thingies are quite nice. I've seen no thread stripping, heard no grinding whatsoever. * It's hard! - This is a 250+ freaking dollar custom computer case. It's for nerds. That said, semi-patient geeks capable of using a screwdriver with access to both kinds, with some forethought, as-in, thinking before doing, totally qualify. The difference between nerd and geek, fyi, is not smarts. It's patience, dedication, and interest. If you have none of the three, or maybe just one and a half of the three, avoid. If somebody else is building the PC for you, kindly !@#$ off and do not review anything that went into the not-you-building-it of your custom PC. Review the builder in that case if you have strong feelings either way. * The dreaded PSU shroud of terror! - It takes 4 screws. Seriously. I hit 5 total because I realized at screw #4 (which was wrong) that, no, this is an expensive case. No way would they charge this much and expect people to try and unscrew at a 45 degree angle twice (not even once, actually). All 4 screws are super-accessible with the side panels off. It's a 2-minute job if you already know how. I didn't spend enough minutes figuring it out to even try looking at the manual so many have complained about. There's two screw heads facing out on the glass side, one facing out on the not-glass side (double-hint: which you should remove in addition to the glass panel before removing the shroud). And one on the not-glass side that actually has its head facing the back of the case towards the left. = Unavoidable-Comes-With-the-Territory-Negatives * It's built for quiet, not for best-possible airflow. I got the huge one hoping to off-set the heat penalty but I'm just running a 3700X and a 2070 Super so probably overkill but I plan on piecemeal upgrading every couple of years on this build with an eye towards discovering whether the absolute top of the line is actually worth it in the end. I suspect I won't run out of fan-space before the case itself is too obsolete to use but for optimal airflow, this is probably not the one. * It really is big and heavy - It has to be. Three reasons. 1. It's about 25% bigger/roomier than a mid-size on every dimension. 2. It cancels noise. Thickness is helpful there. 3. It's modular as !@#$. That's a lot more screws/brackets, etc. * It's a lot on many levels. If you just want a case that's just good enough for the parts you bought just now, it's too many $, too much space, and too much features for just-want-my-things-to-work-now-custom-PCer, which is where I was at on my first build. Agreed on other reviews saying don't get this if you're not sure if you need/want it. I almost got that fractal mesh case. * I've never LAN-partied but this case is a horrible choice if that sort of thing is even still going on (it really is rather heavy - do people still LAN party?). * It's a really silly brand name. But we're all good and bad at specific things. Germany... included.
Overall Review: I wanted it for the big-case-factor, quiet/quality fans, flexibility. No disappointments to date.
