Pros: Let me first say, this case is truly awesome. Not only is it among the best cases available (at any price), but it is also easily the best case I've built a computer in (and I've been building computers for decades). I purposely bought this rather than the pro version, because I don't like windows in my cases - the window on the Pro version is located where you couldn't see it anyway, and not having a window means additional soundproofing for even less noise. And speaking of noise, this is easily the quiestest case I've ever used. Primary heat generators inside the case include a water cooled Intel Core i5-6600, an EVGA GTX 1080 FTW Gaming ACX 3.0 (a very powerful factory overclocked card, which fit *with* the drive cages and other stuff in place, BTW), and 3 mechanical drives. Even when stressing these components, such as when gaming at 4k, the sound is hardly noticeable and temps are not even a concern. Build quality and attention to detail is spectacular. The brushed aluminum finish looks great. It has been hit by my chair many times, and still shows no scratches. Screws and other hardware are good quality and painted black to blend in - a very nice touch. It is well assembled and feels stout. The pieces fit together well, with uniform gaps in the seams. The metal is well formed - smooth, with no sharp edges - with a premium feel. They even provide painted screws so that there is nothing distracting from the aesthetic. Seriously, who does that anymore?!? :) The case is obviously well thought out, with features & options galore - you'd be hard pressed to want more. It supports multiple radiators, and you can even change the positioning of the motherboard to accommodate a thick radiator up top. It has space for numerous hard drives (both 3.5" and 2.5") and fans, and includes intake filters that are both easy to access and clean. It has many holes for cable routing and plenty of space behind the motherboard for wires. And these are just the highlights! Bottom line: I love this case and heartily recommend it. For what it's worth, I also bought a be quiet! power supply and additional fans. They are just as great.

Cons: For me, there aren't any cons. Others might have concerns about the size (it's on the larger side) or price. And, the drive cages are not completely tool-less, but as mentioned in the "Pros" above, be quite! even supplies black screws for the hard drives to maintain the nice aesthetic.

Overall Review: Seriously awesome case. I know it's not cheap, but I can't imagine you will be disappointing. I am now a huge fan of be quiet! The case, power supply, and fans are all excellent products in their categories. They are obviously well designed and thought out, and built to a high degree of quality.

Pros: -Quiet -Great Design -Fan Filter -Silentwings 3

Cons: -Screw are kind of cheap.

Overall Review: Great case overall

Pros: Super Quiet, I have the CPU COOLER and the PSU 1000W from be quiet and it's a great machine. My best Built yet. Can recommend 100%

Cons: to close the door the hard drives wires get a bit in the way but once closed who cares. Would not recommend the open window case for this reason.

Pros: This Case is amazing, I love the fact that it is super quiet it's very modular and roomy case. Love that it has a built in Fan controller. Was able to route all my cables Easy and cleanly. The ability to pull the motherboard tray completely out and flip it around with out hassle for a left handed view instead is awesome and even if you want to you the tray for a test bench works great for that as well. If I could give more than 5 eggs I would. If your looking for a case that can handle a solid water loop I recommend checking this out more room than I honestly know what to do with.

Cons: I can't really think of any other than newegg needs to get on the ball and get the 900 pro of this model would have loved to get the side window than just the standard closed door I want to see my motherboard other than that this was a very easy case to work with.

Overall Review: Great engineering on this case top quality with the modular design and the 3 fans in it are quite check this case out its work the buy if your looking for something quite and sleek.

Pros: As a first time builder, I have little experience with PC cases, however, I was thoroughly impressed with this case from Be Quiet! To begin with, I was delighted with the overall visual appearance and build quality. The brushed aluminum finish along with the outline choices available make a visually appealing setup. The spacious interior made for easy assembly and simplified cable management. The modular design allowed for a wide range of configurations, depending on personal preference. The included Silent Wing fans are almost noiseless and the entire case is built with silent operation in mind.

Cons: The door on the front doesn't always latch properly.

Overall Review: So for I have been very happy with my purchase and will definitely keep Be Quiet in mind when purchasing computer components in the future!

Pros: Good quality, quiet 140 mm fans Heavy indicating significant steel in case Finish in general is very good

Cons: Did not come with all the hardware needed to install an ATX motherboard (missing several hardware items) Case is about an inch too small in height and length. Could not install a 360 mm AIO cooler on the top or front without removing the cage support for optical drives. Some of screws were difficult to attach to the case. Quality control of the case fabrication is not what I expected.

Overall Review: I contacted the manufacture to provide additional hardware that was missing from the case and they quickly shipped me a complete set of screws for the case. Very good customer support. However, as the build progressed I discovered that the supplied motherboard stand offs supplied with the case for an EATX were actually the wrong size and one of the provided stand offs was not threaded so the motherboard screw could not screw into it. Luckily I had leftover parts from a previous build that were sized identically and fit perfectly as a motherboard stand off. The previous case was also designed and manufactured in Germany (Nanoxia Deep Silence 6) and I was expecting something of similar quality. The Dark Base 900 case that I received is a good quality case but it is not excellent quality as I expected. The case was not as large as I was expecting. As noted above, the case can barely support a 360 AIO cooler mounted to the top of the case once the optical drive cage is removed.

Pros: This chasse is very large and has lots of drive bays and slots for expansion cards. It offers many options for you to custom build a computer just like you want it. The Be Quiet brand fans that come with the case are good because they are quieter than almost every other brand of fan.

Cons: The metal is very soft and three of the screw holes for mounting my motherboard got stripped. Also one of the screw holes that keeps the side in place got stripped. I had trouble fitting both a very large liquid CPU cooler and a very large graphics card (GeForce 1080 Ti) so that I could properly configure cooling fans without sacrificing the option to use several of the add-on slots on the motherboard.

Overall Review: If I were building this computer again, I would probably not buy the Dark Base 900 again. I would buy a chasse with a slightly different geometry so that I could have both the large graphics card and liquid CPU cooling system without blocking the way for the other add-on slots while still being able to install a DVD burner and several hard drives. If you are using components whose total wattage adds up to a lot, you will probably need to install several cooling fans in addition to those built into the case, graphics card, and power supply.
