Its a bit expensive but using the inverted layout dropped my operating temperatures considerably. It also has one more PCIe slot than average, so a two-slot second GPU can fit in motherboards with the second x16 right at the end.

Nice looking case, strong and reliable and heavy and big.Very complicated to assemble as the instructions are very basic.The electrical wiring connection setup for the front of the case is not explained as they are not labelled in the instruction manual – just pictures.This case need 2 USB 3.0 sockets on the motherboard but I had to buy a PCI_e to USB3.0 card to slot on the motherboard.Very disappointed by the manual.Had to search on the internet for videos.I am no novice and it would be very difficult for a first-time installer.

been using the 900 for the last 3 PC's now building again with this 901 and loving it great s[ace less screws solid structure, happy I moved up to this one, Lower forward facing drive bay leave no room for standard 140 Fan requires a slim fan if used
This be quiet cases replaces a Dark Base 900, Comparing the 900 to 901 the changes are excellent addressing all of the niggles I experienced with the 900.The case has loads of room for all your kit, the layout allows you to hide you PSU, Cables, Optical Drive and SSD 2.5" drives leaving nothing more on view through the side window other than your MOBO, RAM, Cooler and GPU.There is many accessories with the case allowing you too add an additional GPU cooler to the side of the case and panaels to interchange between solid or mesh fron and top.The front IO panel offers 4 x USB, 1 X USB-C, headphones, mic, fan control and LED control, the latter 2 can be manually controlled or synced with you MOBO, I use ASUS AURA-SYNC and it works really well.The design is ... MoreThis be quiet cases replaces a Dark Base 900, Comparing the 900 to 901 the changes are excellent addressing all of the niggles I experienced with the 900.The case has loads of room for all your kit, the layout allows you to hide you PSU, Cables, Optical Drive and SSD 2.5" drives leaving nothing more on view through the side window other than your MOBO, RAM, Cooler and GPU.There is many accessories with the case allowing you too add an additional GPU cooler to the side of the case and panaels to interchange between solid or mesh fron and top.The front IO panel offers 4 x USB, 1 X USB-C, headphones, mic, fan control and LED control, the latter 2 can be manually controlled or synced with you MOBO, I use ASUS AURA-SYNC and it works really well.The design is excellent and very well manufactured,
Fantastic case huge l can put 2 systems in if l needed to.Unfortunately the front Fans are not working due to a faulty Hub .Have already sent a report waiting for a reply. But the case fantastic easy to build in. Thank you.
Its a very nice case with some great features but unfortunately suffers from weird Be Quiet! issues.First being it has the same cheap quality plastics as their low end cases, very fingerprinty and very easy to break a clip on something etc.Second was the side fan mounting bracket doesn't fit perfectly due to a rivet being in the way without a cutout for it.Third, you can only really mount one radiator in this as it obstructs other placements for fans/rads, even placing one on the top can interfere with CPU Power cabling on your motherboard unless its a super slim radiator.other than that, its a great case, somewhat pleasant to build in but does offer nice features and great cable management with tasteful RGB accents and even support for a 5.25" bay device, ... MoreIts a very nice case with some great features but unfortunately suffers from weird Be Quiet! issues.First being it has the same cheap quality plastics as their low end cases, very fingerprinty and very easy to break a clip on something etc.Second was the side fan mounting bracket doesn't fit perfectly due to a rivet being in the way without a cutout for it.Third, you can only really mount one radiator in this as it obstructs other placements for fans/rads, even placing one on the top can interfere with CPU Power cabling on your motherboard unless its a super slim radiator.other than that, its a great case, somewhat pleasant to build in but does offer nice features and great cable management with tasteful RGB accents and even support for a 5.25" bay device, also looks like it can support an SSI-EEB motherboard which its documentation lacks
Please take note, fans supplied with case are 140mm Silent Wings 4 with 1900RPM!Also case fan speed sync option required BIOS settings change. Set speed control from auto to PWM to make it work.
Overall build is very nice, nicely shaped metal case and glass panel all feel very good with a good deal of weight to them. Wasn't as fussed about the noise cancelling features so the replacement panels for air flow are very good to have, installed those instead in the end, with those and the base fans, air flow is already very good.Feels a lot sturdier compared to other cases I've had before, feel like wear and tear will take longer to kick in with this one.Cosmetic look of the case is great, plenty of room to fit all my parts, got some positive attention from a few folks installing my internet earlier in the week.few things that hold back a five star for me however.- Touch screen controls for fans and lighting are fine, although fan controls are not very ... MoreOverall build is very nice, nicely shaped metal case and glass panel all feel very good with a good deal of weight to them.

I have been building PC,s since the early 90's in highschool and i have used many, many different cases in that time and none have ever come anywhere near the versatility of this case, i spent a whole day taking this apart and trying all the different configurations it had to offer and even found some configs even the manufacturer hadn't accounted for, such is the ability of this case to shapeshift to suit your needs, it cant do everything, but it will try, great subtle lighting fx, great tidy wiring for the case out of the box, also comes with MANY accessories, front panel, side panel and other case options, was expecting great things and great things is what i got, very happy indeed.
