Visual inspection

The Define R5 model has a minimalist design characteristic of Fractal Design and the Define case line, offering endless possibilities for both air cooling and water cooling. The case is black, the HDD brackets, the blades of the two included fans & the 7 expansion slots being white.


The front side of the case is protected by a plastic door which can be opened from both sides of the case, the hinges being detachable.


The front dust filter is removable, behind it we find a included 140mm fan with the option of adding another 140mm fan next to it. Above we find the two 5.25” drive bays and the included three stages fan controller.


On the back side of the case we have a included 140mm fan, below we have the 7 expansion slots and on the bottom we have the space for the PSU.


The side panels are simple and sturdy, the main side panel offers the possibility of mounting a 140mm fan on the side. Also this size panel uses a clever combination of clamps and thumb screws to stay in place.


The inferior side of the case features a long dust filter which can be removed from the front of the case, this filter covers the entire floor of the case, also the chassis rests on four solid rubber & plastic feet.


The top side of the case is metallic, the three detachable panels have sound-absorbing foam on them, these are also made out of plastic. These panels are called ModuVent and can be used individually depending on the cooling method used.
In the front we find the I/O panel and the activity LED of the case. The I/O panel is composed of the following:
– 2x Audio Jacks
– 1x Reset Button
– 1x Power Button
– 2x USB 2.0 Ports
– 2x USB 3.0 Ports
– 1x Activity LED
– 1x Fan controller


The Define R5 chassis has a roomy interior optimized for water cooling and wire management. Below we have a chart that explains the R5’s water cooling options.


The case can accommodate cpu coolers that are up to 180 mm tall and graphics cards up to 310mm in length with the top HDD cage installed. Without the top cage, graphics cards up to 440 mm in length may be installed. Also the wire management holes are covered with rubber grommets.


On the back of the motherboard tray we find two white 2.5″ mounting plates that are fixed using thumb screws.


The wire management process is easy due to the included Velcro straps that hold in place the I/O cables.

The interior of the Define R5 chassis is completely modular, the HDD cages & the 5.25” drive bays are removable being held in place by thumb screws. Also both HDD cages & the 5.25″ drive bays can be moved or removed entirely. The Define R5 chassis features eight 3.5” HDD slots which can also accommodate 2.5” SSDs. Below we have a few photos that show the different mounting options for the HDD cages.



The following system was used to test the chassis:
– CPU: Intel i5 4690K
– Motherboard: MSI Z97 Gaming 9 AC
– RAM: 8GB Crucial Ballistix Tactical
– GPU: MSI GeForce GTX 660 OC Gaming
– SSD: Samsung 840 EVO 120GB
– HDD: Samsung SpinPoint F3 500GB
– PSU: InWin GreenMe 750W Bronze
– CPU Cooler: SilverStone Tundra TD02


Wire management is easy even with a non-modular power supply due to the ample space being the motherboard tray, this space measures approximately 36mm.


Installing the storage devices into the HDD metallic brackets is done with ease, using metallic screws and rubber washers to reduce the amount of vibration.


Installing a SSD into the chassis is easy due to the two dedicated brackets mounted on the back of the motherboard tray.


The noise level for the two 140mm fans included with the chassis using the included fan controller was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.


Final thoughts

The Define R5 model is a perfect example of Swedish quality & precision characteristic of Fractal Design, offering ample space for installation and cooling.
The Fractal Design Define R5 chassis manages to bring back to the consumer’s attention the Define series using the characteristic Fractal Design stylish look, the Define series becoming the calling card of the company.
In conclusion the Define R5 model is an excellent case, the materials used in its construction being high quality. The interior space is used at maximum potential offering numerous expansion options and can house a complex water cooling or air cooling system. The installation is done with ease and the included two 140mm (Fractal Design Dynamic GP14) fans and the integrated three speed fan controller add more value to the case.
