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.

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.
