Take advantage of a modular layout and easy access with the Define R5 Mid-Tower Case in black from Fractal Design. Featuring ample space for components and convenient entry via the side and front of the case, the Define R5 is intended to provide a computer case that fits your build. Two removable, external 5.25" drive bays sit behind the hinged front panel. Inside the case, there are eight bays accommodating 2.5 or 3.5" drives, as well as two mounting positions behind the motherboard specifically for 2.5" SSDs. Seven expansion slots are also present, so you can install plenty of adapter cards, including a GPU up to 12.20" when the case is in its default configuration. However, by removing the top HDD cage, users can install graphics cards up to 17.32". CPU coolers up to 7.09" are also supported, as are PSUs up to 11.81" in the default configuration. However, PSU size is limited to 6.69 or 7.48" when a 140 or 120mm fan is installed in the bottom of the case.
The Fractal Design Define R5 comes with two preinstalled Dynamic GP14 140mm fans, including one at the front and one at the rear of the case. In addition to these fans, users can install up to three fans at the top of the case, up to two on the bottom, and additional fans on the side and front of the case. Or, if you prefer water cooling, you can install radiators instead. Radiators up to 360mm can be installed at the front of the case when users remove drive bays. Similarly, the top of the case can accept radiators up to 420mm when the 5.25" drive bay cage is removed. However, with the drive bay in place, you can still fit radiators up to 280mm. When installing a 420, 280, or 140mm radiator and fan at the top of the case, total thickness should not exceed 2.16". Both 120 and 140mm radiators can be installed at the rear and bottom of the case, though using radiators at the bottom of the case limits PSU size to 6.49".
Featuring a quick-release locking mechanism on the left-side panel, the Fractal Design Define R5 also sports a right side panel with captive thumb screws, allowing for easy access. Additionally, users can open the hinged front panel to access the front fan, external 5.25" drive bays, and dust filters. The hinged panel can also be configured to open from either direction. Complementing this accessible design, the Define R5 also features sound dampening and ModuVent covers, allowing users to cover unused fan vents and decrease operational noise. A three-speed fan controller is built into the case and provides control for up to three fans, while a front I/O panel provides you with two USB 3.1 Gen 1 and two USB 2.0 Type-A ports. Separate 3.5mm ports for audio input and output are also present, as are power and reset buttons and a drive activity LED indicator.
