be quiet! Dark Base Pro 900 Reviews
Superb Design
Just about any combination can be achieved with this case. Yes, it's complex as others have said. However, if you're up for the challenge, you build the monster computer and show it off from either side.
Excellent cooling, bit of a pain to assemble
Build itself is of excellent quality, but kind of a hassle to work with. A lot of screws to undo every time you want to do anything at all, and taking the panels off is quite annoying each time. That said, I'm getting great temperatures even with stock fans, noise is fairly low, and I'm loving the HDD trays which are easy to install and stay in place very well. Cable management is also pretty easy, unless you have a large motherboard. I have a EATX, and it covers the rubber holes the case provides for routing cables from one side to the other, which is kind of a bummer.
Good but not great
The pros: -expansive insides -room for multiple large radiators -includes some quiet fans -highly flexible installation options -quiet The Cons: -EVERYTHING is screw based. This case does not know the meaning of toolless.. including drive bays that by the way you have to disassemble a good amount of case to get to screws on the non window side -power supply mounting is a bit weird and with it being so low in case you are almost guaranteed to need extensions -limited places for cable management on rear of motherboard which makes putting the case door back on difficult -HEAVY and limited places to pick it up easily -feels dated on inside
Awesome
Great piece of art!
The worse case you can buy
The case manual is about 5 pages doesn't explain anything you are on your own most of the screws break when you try to remove them It was a nightmare I wish I took a different case B&H have the best customer service they are their to help you great store
Great Case!
Great case. I will definitely buy it again. Pro ... - large - Quiet when needed. - Fans are not that loud on Performance mode. - Completely reconfigurable. You can move the motherboard and everything else to the other side - no problem. Watch the videos. Cons ... - if you plan on using a DVD/CD Player it will be an EXTREMELY tight fit with a 360mm radiator / liquid cooler. Only one DVD/CD player will fit with this configuration. - get rid of that back support leg on the PSU cover. It is a tight fit without it. Leaving it in place will pull on wires when installing/removing it. - if you drop a screw it will get wedged in unexpected areas. This caused a lot of wasted time fishing them back out. - one of the USB ports (front panel) is too tight. Almost impossible to use.
Hugely customizable case
I picked this case because of the built in wireless charger. I thought that was neat. I also wanted a nicer and bigger case than my last one. This one can actually close both side panels with my hybrid cooled graphics card in there. Took one star off for some screws that were much too tight and then stripped :(
Quality top notce, documentation poor, design flaws
I regret my purchase. This case is so unnecessarily fiddly, fussy and time-wasting. The documentation, both written and in videos, appears useful until you try to ACTUALLY do a standard build. Instead of 2 minutes to install a PSU, count on 2 hours. The process is not documented but you have to remove the PSU shroud and remove 3 ventilation panels in the rear for access to the PSU rear which is well inside. 4 of the 8 screws that hold these panels in place are accessed through an extruded chassis tube. If you drop a special screw inside this tube, and I did, there is no way to retrieve it since the tube is closed. Removing the 3 top panels of the PSU shroud is undocumented, though they are shown levitating in the video. It turns out to be a simple job that could have been documented in a single sentence, but since they are plastic you hesitate to try all the possible ways to remove them. The 2 ODD bays each have mounting screw holes, but of the 16, only 10 are accessible without disassembling the case. These are design errors that every other case I've used did not suffer from. The company needs to beta test their products with real people. And the emphasis on completely disassembling the case to reverse the sides, which will apply to 1% of the customers due to the extra week of work, is the one and only reason to choose this case. If this is the target customer, I say just build two versions and save a lot of misery. Build quality is perfect.
