Pros: Ultra cutomizable, could not test other features so far

Cons: People already complaines about the screws, well, they are three screw I cannot remove. The small ones used for the PSU cage and the rear slot brackets. So there's basically no way I can properly install the PSU When you spend that much in a high end case such a lack of quality is inexcusable. What I am supposed to do, return the case half way being built ? How does such non quality (3 screws tighted so hard even an electric tool cannot remove them) cost the compagny ?

Pros: This case is large and very well thought out. - High quality materials - Nice finish on the exterior - Noise dampening insulation on the interior - Quality rubber gromits on some key hardware. - The rubber material is excellent (no cheap stuff, no odors) - Extra brackets, hardware, velcro straps are a nice inclusion! - The first thing I did was disassemble it to the bare skeleton. At each and every step of the process I was impressed with the durability, and rigid design. I'm very mechanically inclined and work with complex things on a daily basis, the way the case disassembles and reassembles is very intuitive. - I plan on water cooling with a custom loop. The amount of room this case has makes options nearly limitless. - Orange and Black. Oh man does it look nice. I'll be honest, it was the color scheme that made me click on be quiet! when I first noticed their company. I really really like orange and black. This thing is going to look sick with clear borosilicate glass tubing and orange coolant. (I'm going to need a window: See below) - Got it on sale!

Cons: Not major at all, but worth mentioning: - Out of the factory, some of the screws are really snug. Not an issue if you are smart about how you apply torque. Worth mentioning, because I'm sure someone will ruin a screw and blame it on the manufacturer. Just grab the right bit and apply slow steady torque and you'll be fine. Don't over-tighten things on re-assembly and you will never have to worry about it again. - Some of the hardware screws were clearly stressed by how snug they were installed. - No case window for re-sale for the non-PRO version... yet

Overall Review: In an email to bequiet, it sounds like a window may be available for resale in the future, making the 900 a great choice over the PRO version. - By the way. be quiet! responds to email very quickly. I was just making a product inquiry, and had a response within 12 hours. Way quicker than I expected from a country half-way around the world. I'm eastern time zone US, I usually have to wait more than 24 hours if I deal with local companies. I'm left feeling confident about future purchases with be quiet! I'll be all for a windowed side-panel when available. Note: I've seen some people mention an issue with the front panel door. I have no idea what their issue is. Mine works and stays shut. It is basically a magnetic latch. The materials are all high quality and sturdy, if I tip the case so the front is angled down, eventually gravity will win and the door will fall open. I suggest placing your PC on a level surface and if that doesn't solve it, adjust the hinges. The door panel can be switched so it opens the other way if you wish. I highly recommend this case for anyone that wants a case that will last for several different builds and wants flexibility with internal components... and doesn't want to hear their machine running!

Pros: - Minimalist exterior design that looks great. - Fantastic well laid out case that's easy to work on. - Case is extremely modular, You can arrange things so that your motherboard is on the left side of the case instead of the right. - Plenty of room for hard drives, cpu coolers, graphics cards, radiators, etc. - Many of the screws are the type that will loosen but not fall out - Sound dampening material inside of the case, along with design features that also reduce noise. - Filters in front of all the case fans that pull air into the case - Case is very sturdy - Even the feet are removable if you choose. - Came with velcro strips! - Power light is a calming orange, and not an eye-searing blue.

Cons: - I wish there was a little bit more room behind the plate the holds the motherboard for cable routing. - I also wish some of the cable routing options were a bit more obvious - The case is almost too quiet. - Some of the screws will strip if you use the wrong size bit. I almost stripped the screws for the power supply bracket before I figured out the correct bit I needed to use. - Hard drive bays are a little strange to pull in and out. It'd prefer more of a rail system, but that's pretty minor.

Overall Review: Make sure you are prepared for the size of this case, it's big! I really like the dark brushed metal, and the smooth almost minimalist design to this case. I chose this particular model of the case because I didn't want a clear panel on the side of my machine. I'm probably in the minority, but I really prefer not to have the glowing guts of my machine on display. It's hard to overstate how modular this case is. I only took small advantage of that by rotating the plug for the power supply 180° so that it would more easily line up with my power supply. Oh as a note, the front panel doesn't latch. It's just a push pin that will pop the door out when you press in. This isn't a issue except when you're tilting the case forward. Just something to watch out for.

Pros: Extremely versatile and well designed and built. Quiet. Great service. The professional reviewers were right to recommend this as the best, or one of the best cases for 2006. Quality German engineering.

Cons: The power LED light went out, but the switch worked. Got a prompt replacement from be quiet!

Overall Review: Have been putting together computers since 1992, and this is by far the best case. As many reviewers have noted, the case is extremely versatile, well engineered, and made of quality components. The indirect bottom, top, and front vents contribute to a very quiet case. I have 1 bottom, 3 front, 3 top, and 1 back fans, and the noise is barely perceptible. The all in one water-cooled MSI GTX1070 and Corsair H115i radiators are mounted at the top so had to move the motherboard mount down one notch to make room. Some have complained that it is hard to put the mount back on the case, but just moving the mount down was very easy. The hard/SSD drive cages are individually mounted with spaces in between instead of in large cages, so I only used 3 which greatly opened up the ventilation space near the front. Since almost everything is movable inside, it is future proof. There are many elegant small engineering touches such as hand screws being held by cages and panels so as not to easily get lost. The fan control/power module had extra connection for 3 additional fans in addition to 3 that came with the case. A lot of thought went into designing this case. I probably won't have to buy another computer case again. The power switch orange LED went out after a day (the switch worked fine) but received a replacement in the mail after I contacted the be quiet! The service was outstanding. I usually don't write reviews, but this case was special enough to warrant an effort.

Pros: Fully tool-less design. Very spacious and easy to configure for your needs.

Cons: No cons for me.

Overall Review: I would recommend this case to others. I like the Pro design also. I think I'll buy the Pro model as well and set it up as a server for the home.

Pros: -Very modular. -Good quality materials. -Quiet with good temperatures out of the box (the Silent Wings 3 fans are great). -Filters are easily accessible from the front of the case (the case is big and heavy, and I'm glad I don't have to move it every time I need to clean the filter on the bottom). -If the person removes the drive bay cage, they can have 3 X 140mm fans in front, which should provide great airflow for just about any build out there. I ended up doing that for my front fans, and I installed another 140mm fan in the back, and another on top, and my temps are actually really good, and I can't hear any of the fans.

Cons: -The manual provides little-to-no info on changing/removing parts (like the drive bay cage or PSU mounting for example). -Only 9 stand-offs included (my ATX motherboard uses 10), but I had extra. However, cases this expensive should come with a couple extra. People with larger motherboards like an EATX might not have enough included stand-offs.

Pros: - Bought this case because it was big and I was building a all-in-one virtualization machine, media center and gaming rig - Installing everything in this case was easy since it was so large - Ample space for may hard drives so it is great for media server

Cons: - Thumb screws for the HDDs and the case side panels are not threaded very well. Be very careful not to strip them. - Other screws in the case were so tight that I had to take super extra care not to strip them - The polished aluminum looks amazing but it is a fingerprint magnet (however I knew this before I purchased based on other comments) - Fan controller on the bequiet Dark Base 900 gets power by sata so they never show up in the bios. I can only control them using the fan controller.

Overall Review: - I like how quiet the case is but all of the cons I listed were to much of a pain for me to ever buy this case again. - Once the screws are stripped it makes it so much harder to work on the case.

Pros: - Solid strong steel - Has many modular options, including the ability to flip the configuration entirely - Has lots of HD housings, which are modular and can be removed one-by-one. I also removed the optical drive bay completely (once I realized I hadn't used my optical drive in over a year anyway) for better airflow. - Has lots of room for mounting fans of various sizes

Cons: - Not much space on the back side; meaning the space between the mainboard and the rear side panel, which is where I usually hide most of my cables. I've seen cases that have lots of space back there for cables, and even regular hard drive mounts, which this case only has a single SSD mount behind the motherboard in an awkward spot. - There is a strange housing that you have to mount the PSU into, which is separated from the back of the case. That means that you are required to connect a very short cable that's included with the case to connect the PSU housing to the power plug on the back of the case. I haven't seen that before but it was weird and I'm unsure why that extra PSU housing is used at all.

Overall Review: - I prefer to mount hard drives on the "back" between the mainboard and the rear side panel (for better airflow) but that cannot be done with this case.
