Incredible Case 5/16/2020 1:58:02 PM

Pros: Excellent Airflow & Sound Dampening

Cons: None

Overall Review: Case has excellent airflow and sound dampening - stock fans are doing their job admirably.

A coffee maker running on the opposite side of the house is louder than the computer right next to me.

This case was a pleasure to build in, by far the best case I've ever had.

Quiet, with intelligent design 5/14/2020 7:42:22 AM

Pros: Really nice cable management features
Every piece comes off, so installation is a breeze as you can reach any part of your case
Very quiet, in part because the fans are high quality, and in part because if you use the provided fan hub, they are tied to the speed of the cpu fan (from what I can tell)
Fits my huge Scythe Ninja 5 CPU cooler with room to spare
I LOVE how the SSD's attach.

Cons: Bigger than anticipated despite looking at dimensions
Removing the top panel for access to things like CPU Power terminal is a bit fiddly
The sound absorbing material does very little for lower frequencies (which is really physics' fault, not the case, just know that it's sonic performance is not as impressive in lower frequencies)

Overall Review: I love this case. It's the first "silent" case I've been really happy with, design-wise. It also does fine thermally, though I'm running a R7 3700x and a GTX 1060, at near-stock speeds, so I'm not really pushing the thermal load all that much. CPU idles at 33C and loads at 55C in normal ambient temps. I'm sure a more aggressive case could get those numbers down a few degrees, but I needed silent and that's what I got.

Minimalistic and modular design but faulty 4/29/2020 2:44:16 PM

Pros: It hosts an optic bay
Fits pretty much any GPU
Has enough room on the back of the mobo side to fit the annoyingly thicker cables
Has a USB-C connection

Cons: Power button is extremely weird. Very little travel and odd feeling, I dislike it
It has a built-in motherboard "slot in" mount which, in my case, led to a very tough time lining everything up (3 of the 8 screws were extremely difficult to connect, 1 impossible) and leaving room with the I/O cover
My case came with a broken metal lock hinge!

Overall Review: This is my third Fractal case and I've always had a nagging issue here or there. This one falls in the middle but for the price, it should be flawless. My case came with a broken metal hinge on one of the doors (you snap it into place, not slide, which is awesome on paper but mine's broken). That hinge is extremely thin metal and if one of the four (two on each door) was broken from the factory or shipping, I can imagine the others may be at risk over months or years.

If my replacement case is "perfect" regarding the hinges and hopefully the power button was also a faulty piece instead of a feature, and the built-in mobo mount fits better, I will bump my rating.

Gorgeous looking case 4/28/2020 10:55:34 AM

Pros: This is my 3rd Fractal Define case and they are, as far as PC cases are concerned, just fantastic.

Fans are easily accessible for cleaning and placement is variable.

Side walls come off with just the right amount of pull but also snap into place securely.

Cons: Fractal's isn't responsible for design flaws that are industry based (like how the length of cables relate to motherboard layouts and or how GPU lengths dictate placement of HDDs) and the case does its best to accommodate these.

Still there are some things Fratcal could do better - for example why does it have to be so tedious to put a hard drive onto the metal slide and then the slide into the case? Or why is it impossible to plug in new cable into the power supply once it's mounted in the case?

Overall Review: As good a case as one can expect for PC parts.

Great design and excellent quality 4/28/2020 7:10:40 AM

Pros: - Very flexible layout. If you are debating whether or not to spend money on a liquid cooled system, this case is perfect. If you have plans to add a lot of drives, it has the room. Conversely, if you plan to eliminate all your old HDDs, you can remove the entire drive bay and open up the case even more.
- Smart fan controller which connects between the CPU fan and motherboard allowing it to intelligently control the other case fans.
- Convenient controls including USB3 and USBC at the top leading edge where it is perfectly placed for a typical deployment under the desk.
- Serious sound dampening - the panels are heavily padded making for a weighty case and it really does make an appreciable difference. This is not the chassis you want to carry to LAN parties! (The UPS driver tumbled the 15kg box rather than lift it - but no harm done.)
- excellent manufacturing quality and a generous supply of black fasteners.

Cons: - I would have appreciated one or two more "wall-mounted" SSD mount points. (Although there is plenty of room for them in the numerous HDD bays.)
- Ikea-style pictographic instructions are pretty useless - but thankfully not essential.

Overall Review: The last case I bought was an Antec mid-tower that has served me well for more than 15 years. However, its crammed interior and lack of cable management severely impaired airflow which in turn increased fan noise.

The R6 illustrates how much case design has improved. I completely understand why some people make their case the centerpiece of the room. A younger me would have loved the glass paneled version of this case and spent a small fortune on LED lighting. Today, I have a more utilitarian approach but this case has both brains and brawn to complement its beauty.

Excellent case, great quality, very well designed, can use with multiple radiators, and very quiet! 4/25/2020 8:39:45 PM

Pros: High quality, very well made and excellent design allowing for very versitile setups from 1-7 fans, and also accepts 2 radiators of just about any size up to 420mm
Lots of room inside for cable management and I have 2x M.2 PCIe SSDs, 1x 2.5" SSD, and 4x HDDs which are all hidden under the power supply shround or the front section of the case so none of them are visible!
Top of case can removed for greater airflow with a grate, a dust filter, or a solid panel for silent running.
Tempered glass side panel is easy to remove but locks in place securely.
I'm running a 280mm radiator at the front with 2x 140mm Enermax TB Silence fans on it, 1 more 140mm Enerrmax TB Silence fan at the rear of the case with the solid panel on top, I keep the front door closed, and my computer sounds totally silent but still has enough airflow to game on an overclocked 9700K running at 5.1GHz + RTX 2080 Ti pushing 240 FPS to a BenQ Zowie monitor without overheating.

Cons: It is a little large (long). It could be a few inches shorter front-to-back, and shorter height-wise and only lose a few 3.5" bay spaces but I'd still be able to run my current 4x HDD setup with room to spare. The case is made for something like 10 HDDs which seems like too many for the average buyer's wants/needs. I think 6 drive bays would work fine for more than 99% of the population.
Some of the screws seem to be machine-tightened where they are over-torqued and some of the PCI slot cover thumb screw threaded receivers may be 1/2 stripped from the factory. The case was also painted after some of the screws were put in place so they are very difficult to remove because the paint on the back side of the threads makes it impossible to unscrew a few of the thumb screws without the use of a screwdriver the first time to break the paint off those particular thumb screws.

Overall Review: Excellent case, excellent build quality, excellent versatility so you can configure the case almost any way imaginable, and lots of room for 10x 3.5" drives plus like 4-5x 2.5" SSDs lol!

Love this case 4/25/2020 4:37:47 PM

Pros: Best cable management I’ve ever seen
Dead quiet, can’t hear a thing!
Solid construction, very high quality

Cons: Heavy
No cable routing from top of PSU shield, not critical as there are many other routes, but would make connecting to PSU much easier...shield was not removable that I could tell.

Overall Review: Excellent case, couldn’t be happier with this purchase for my new build. Quality is amazing, and the noise reduction on this case makes it absolutely dead silent.
