Pros: It's nondescript and quiet, exactly as advertised. You can put it in a room with other people and they'll barely notice it's there. Comes with 3 large case fans that will be plenty for a lot of builds, and has room for several more. Has an optical drive bay, which is removable if you don't want it. Dust filters are easy to remove and clean, including the one on the bottom for the PSU (and an optional fan). Build quality is excellent. It feels sturdy.

Cons: I find the PSU shroud more annoying than useful and the instructions don't explain how to remove it (not sure if you can). Cable management paths make some of the cables a pretty tight fit, although they did all fit.

Other Thoughts: Did a build with this case today. It passed the most important test: my wife can barely hear it at all. It was pretty easy to work inside and had clearance for a big Noctura cooler, so that's nice. If you need something that will give you decent airflow while being quiet and fitting nicely into a room, you should get this case.

My previous build was in a R5. The Fractal brand has been a pleasure to build in. I appreciated the already placed ATX stand offs as well as the offerings to modify the case to your needs. I went with a m.2 complete build this go around, so I removed all drive bays to maximize my airflow. Compared to the R5, I like the top and how that dissembles. Only issue I ran into was that he HD Audio cable was unplugged at the top. I had to get a pair of tweezers to help plug it back in since it's so narrow.

Wanted something subdued, practical, simple, and quiet. Fractal was the best choice.

Spacious, highly flexible and sturdy. I will note, however, that the plate which covers the top vent was a pain to remove, and some of the standoffs weren't as easy to tighten down as others.

Simply fantastic. deserves 6 stars. Can't recommend enough. Build quality is fantastic, flexible design, good airflow and quiet. Dust filters everywhere. Heap of well designed drive trays. Great cable management. Was easy to work in.

A really neat feature is the screwless closing mechanism for the side panels. Definitely want this on any case I buy in the future.

Had a minor issue with the front panel audio and customer service straight up offered a replacement. Brilliant.

For some it might be a bit large. And it is really heavy, but I am not moving it much. Got it for a good price but worth full price ($209).

Excellent design and extremely quiet. Lots of room for customisation and ability to remove parts. Manual explains clearly how to remove things. HDDs and SSDs all require screws to mount them to their trays, which is less convenient than cases I've had in the past which have toolless installation and easily swappable trays. If you get the USB-C version, make sure your motherboard also has an appropriate header for that, otherwise save money and skip it. Only space for 1 x 5.25" drive bay, which is one less than offered by the Define R5. If you fill this bay with an ODD, expect that cable management is going to become tighter in the top corner, and will require more thought. The limited number of LED lights are not intrusive and are perfect for people who don't want a flashing disco to be taking place at night, especially when leaving the machine on overnight to render.

Heavy, beware of back pain and carry it properly, especially after your components and HDDs are inside. Recommend paying for a courier to ship this, it was far too heavy and wide for my arms to carry. If you can save money and do free instore pickup for the rest of the components, pay to ship this.
