As the name implies, Define Mini is the smaller sibling of the acclaimed and award winning Define R3 case. Being a Micro ATX version of Define R3, it offers a number of interesting functions with a very stylish appearance. It's a case focused on low noise level, without neglecting other important features such as cooling, expandability and ease of use. The Define Mini excels in including a lot of features in a small size!

The patent pending feature ModuVent, in which you can choose whether to have fans installed at the side or top panels, makes the case appealing for users seeking optimal silence, as well as the performance hungry users.

The sleek black interior is matched with pre-fitted, dense noise-absorbing material on the side panels, efficiently absorbing noise and vibrations.

You can fit an astonishing total of six hard drives into this case, using the user friendly HDD-trays which are finished in an attractive white colour and use black silicone mounts. The PSU is mounted in the bottom of the case, with a convenient pull-out filter beneath it.

Tangled cables are a thing of the past as the Define Mini offers an innovative, convenient and great looking way to hide them. The motherboard mounting plate has rubber covered holes through which you can easily route the cables to a compartment which has more than ample storage space located behind the motherboard.

Customer Reviews

Superb Case


As with all Fractal gear, the build quality on this is great! It's a tad on the heavy side, but in a reassuring way. The 2 drive cages work well and the top one rotates to aid with air flow. (Top Tip : Remove the top drive cage and get amazing airflow all the way through the case). The fractal fans are OK but not totally silent. If you want total silence, look at something like the Noctua ones and a decent fan control system. Scythe Mugen 2 Rev B cooler fits this case no problem. There is an additional vertical slot just next to the four regular ones, which could have been useful except for the fact it is recessed in a quite narrow gap. Cable routing is excellent and if you take your time working on this sensibly with a few cable ties, you can achieve a great job with loads of clear space left for airflow. Overall this is a superb quality case and an absolute pleasure to work with. 1 star dropped for the less than useful vertical slot.

Solid, silent and great service


I was waiting ages for this to be released and after signing up for an email alert it eventually came in! I am very happy with the case, I knew it was exactly what I was after anyway but I was not disappointed at all with it. The build quality is nice, the cable routing is excellent and the soundproofing is also great. It comes with a variety of screws and fixings and a fan controller for the 2 installed fans (can add an extra 2). There is a bit of hum from the fans (I had expected complete silence form them at the lowest setting really). All in all very good and excellent service from quiet pc.
