Interior and Build Notes
First we need to remove the side panels, and this is particularly easy as both sides are tool-free.
The case does ship with thumbscrews installed on both side panels, but these are for transport only as the panels do securely latch, and you simply pull out to release each side.
The rear panel is lined with noise damping material
With the panels off we see a different interior than the previous Define cases, and it’s quite clean.
The motherboard tray supports up to EATX, and there are plenty of grommeted cable routing openings to keep the build looking tidy. The right side of the component chamber is dominated by a metal partition, and with this removed we see the storage trays.
Each of these trays with hold either a 2.5 or 3.5-inch drive, and is accessed from the back as we will see next.
Turning the case around now we see that stack of storage on the left side, with the new PWM fan hub in the upper middle alongside the top of the velcro cable management strips, and then the two dedicated SSD mounts behind the motherboard tray.
There is sufficient space for easy installation of large air coolers and various liquid coolers (not to mention custom cooling – though I didn’t go down that road), and I tried a quick mount of my trusty 240 mm AiO system (Corsair H100i GTX) after I had the motherboard in place.
The top fan mounts in cases often provide less than ample room for a radiator and fans without clearance issues, but here – as with other Fractal Design cases I’ve reviewed – there were zero problems. With the cooler mounted there was a generous amount of room all around, making larger liquid cooler installs possible.
What about up front? If you need or want your radiator up on the front fan mounts that is certainly possible, and access is easy once the storage trays have been removed (and that front trim panel as well, if you need access from the component side).
There is support for bottom-mounted fans and radiators in addition to rear/top/front, making the Define R6 quite a flexible option for custom cooling.
The power supply install is easy thanks to a separate bracket that allows it to simply slide in and then connect via a pair of thumbscrews:
Storage is straightforward, beginning with the HDD/SSD trays.
The holes for HDD screws have rubber grommets to control vibration, and installing the mounted drive on its tray is easy with the captured thumbscrew. The back of the tray fits into place with a shaped plastic foot, and then it is secured against the case with the screw. I did notice a slight sag on the open side of the drive tray, but nothing serious.
SSD installs can be made with the same HDD trays using the alternate screw holes, or via dedicated SSD brackets behind the motherboard (the floor of the component side is another alternative for SSD mounting).
With the system together it’s time to check out case temps and noise levels.
