Designed from the ground up, the Define R6 goes beyond iteration with a profound stride of innovation—the latest and largest step in the legacy of the world-renowned Define Series.

Sound-dampened steel panels encase a fully redesigned interior with more storage capability than ever before, and with nine fan mounts, a PWM fan hub and 420mm radiator support, the R6 is the perfect platform for building your dream water loop. Improved third-generation ModuVent™ technology allows an effortless transition from the metal-clad, sound-dampened top panel to filtered high-airflow, multi-fan ventilation.

Expanding on the timeless elegant form and silent modular function that brought so much success to its predecessors, the new Define R6 offers the most demanding hardware enthusiast a solid foundation and flexible framework with limitless potential.

One More Design Mod Suggestion 12/7/2019 7:41:00 AM

Pros: Nice build quality

Cons: Top Panel Venting
Non-removable power suplly shroud

Overall Review: Finally got around to installing an EVGA 280mm CLC 280 AIO cooler in this case under the top panel recently. This case has a removable top panel, and I noticed that with the top panel removed my CPU temps were about 8-10 degrees centigrade lower under high load than with it on. There are no top panel vents on the case. Other cases I have (the NZXT H630, for instance) do have top panel venting.

Another design mod I would like would be to increase the open space UNDER the top panel to accommodate another set of fans to allow a push-pull cooling setup. I was able to do a push-pull setup on the NZXT full size tower with another EVGA CLC 280, with all of the fans inside the case (wouldn't fit under the top panel either). However, I didn't even try to do this with the smaller Fractal Design case - it looked way too cramped.

Together, these two mods would I think significantly improve the case's thermal performance. You can always pull drive cages out, remove your optical drives, and install the AIO in the front on a lot of cases. But if you want to install an AIO on the top of the case, these mods IMO make sense.

Manufacturer Response:
Hello John,
The Define R6 features our third-generation moduvent, which lets you choose between a soundproof steel cover or filtered multi-fan ventilation in the top panel. Have you tried separating the steel cover from the plastic ventilation panel? If you encounter issues separating these two panels, please reach out to us at your earliest convenience via https://support.fractal-design.com/.
Best Regards,
Andrew Leibman, Fractal Design

Love this case 12/7/2019 5:32:21 AM

Pros: Looks great, easy to run the wires, very configurable with lots of drive and fan options.

Cons: Glass panel makes me nervous about dropping it some day.

Overall Review: I have not bought a new case in a long time. Shopped for almost a week before deciding on this one. It's expensive but I love it.

Modern, attractive, and still offers a 5.25" drive bay! 12/5/2019 11:58:20 AM

Pros: Plenty of options, very attractive, and builds clean.

Cons: Maybe a little tight in some areas when connecting the motherboard pins, but that's about it.

Overall Review: This system has been a fairly easy build. The finished project looks like it came from a manufacturer. This case has a lot of drive bays, both for 2.5" and 3.5". A full-sized ATX motherboard fits easily, and there is no confusion on where to mount the standoffs for placing the motherboard. In one of the drive bays, there is an accessory box containing all the screws and ties needed for assembly. A full owner's manual is included, which explained everything I needed to know about how to mount all my devices. This is a durable case, the components are of good quality. It is built to last. I believe this is well worth what I paid.

Incredible quality 11/19/2019 8:32:23 PM

Overall Review: It's been a good 10 years since I've built my own PC. The quality and features have really improved. This case is no exception. I am so pleased with it.

The one thing that got me - is wanting a USB-C front-panel port, but very few mobos have that capability. Have't figured out a soln for that yet.

A Fantastic Case Thats Beautiful and Functional 11/16/2019 4:16:00 PM

Pros: - Lots of built into measures to make cable management easy
- All case fans plug into one single controller
- Tons if room for full sized cards, full sized motherboards, huge coolers, ten plus case fans
- Removable dust covers on every intake
- Sleek and simple

Cons: - The manual was pretty barebones and could use some words. The way to do things were all shown with one picture rather than a series of images which made it kind of hard.
- If you convert the case to the open layout then your optical drive doesn’t fit very well and you can only screw it in on one side.

Overall Review: 100% a great buy

Best case I've ever built in 11/16/2019 1:17:35 PM

Overall Review: You're pretty much able to build anything in this case from a simple system, to a monster custom rig. It's super easy to configure the way you want for your specific build and simply exudes quality. It's just about ruined other cases for me.

Pros: solid design in build quality plenty of space for cable management.

Cons: a little bulky but any case that can fit this many drives usually is and the slots on the side of the front show some plastic bits if you look at it.
