Define Mini

The Define series is reaching new heights in combining stylish, contemporary design with maximum functionality and noise absorbing features. The minimalistic, yet stunning front panel design, fitted with noise absorbing material on the inside, creates an aura of exclusivity.

As the name implies, Define Mini is the smaller sibling of the acclaimed and award winning Define R4 case. Being a micro ATX version of Define R4, 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 fan slots in side and top panels open or not, makes the case appealing for users seeking optimal silence, as well as the performance hungry ones.

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. All painted in a nice white color and using black silicone mounts. PSU is mounted in the bottom of the case, with a convenient pull-out filter beneath it.

"I have to say that throughout the experience the Define Mini did not reveal one single sharp edge, not something you can say of every PC chassis these days. It is a very well constructed, well finished and genuinely classy piece of kit that will make any enthusiast PC builder very happy indeed. At around $120, it’s not cheap but to be honest that is kind of the point. We give it our hearty recommendation and the VRWorld Gold award."


"В сухом остатке Fractal Design Define Mini является качественным корпусом, подходящим для установки материнских плат Micro ATX, топового процессора с хорошим башенным кулером и одной топовой видеокарты."

"Dette kabinet kan man kun blive forelsket i, det er lavet så det fanger ens øjne og kan både bruges på det flotte kontor og i den mørke gamer-hule, så det egner sig til alle forhold. Én ting som er noget der virkelig fanger mig ved denne serie, er at der er monteret lydabsorberende materiale i hele kabinettet direkte fra fabrikken af, så det er optimeret til at opsluge så meget støj som muligt, det er ikke noget jeg har set ved ret mange kabinetter fra andre producenter."

"Un completo gabinete con mucho estilo y elegancia en un formato pequeño, se presenta el Define Mini, perfecto para aquellos ambientes minimalistas y que requieren de poco ruido para el ambiente laboral. El manejo de cables se facilita con los grandes espacios escondidos dentro de la estructura. La remoción de una parte de las bahías brinda flexibilidad al uso de este gabinete. Los filtros de ruido en espuma representan un complemento especial para apoyar la idea de sencillez de Fractal Design."

"Fractal Design hat mit dem Define Mini ein sehr schlichtes, gut durchdachtes und gut verarbeitetes Gehäuse auf den Markt gebracht. Die beiliegende Lüftersteuerung ist nützlich und erfüllt ihren Zweck einwandfrei. Filter vor den Lüfteröffnungen schützen die Hardware vor Verschmutzung. Jeder der Wert auf ein dezentes, leises Gehäuse legt, ist mit dem Define Mini sehr gut bedient. Die kompakten Abmaße lassen eine unauffällige Aufstellung zu und erleichtern LAN-Party-Gängern den Transport."

"The Fractal Design Define Mini deserves the same score as the Define R3. The case is a successful attempt at offering the exact same features of the bigger cases as a compact mATX variant. On top of that the Define Mini finally is the first of the entire Define series to ship with internal USB 3.0. Besides that, it is commendable that Fractal Design has managed to keep the fan layout the same, include the six hard drive bays and virtually transport each feature of the Define R3 or XL in the Define Mini. On top of that, as it should be with a smaller chassis, this case naturally costs less. Thus it is just as good as all the other Define cases out there and perfect for those who want a silent enclosure but with the compact dimensions of a micro-ATX system. The only downer is the fact that the Define Mini is only available in black."

"Fractal Design Define Mini kabinettet får samtidig en editors choise award, for de ting som producenten har formået at udstyre kabinettet med af features inden for et minimalt pris budget samtidig med at kabinettet har et super interessant design. Måske blandt de fedeste MicroATX kabinetter jeg personligt har arbejdet med i midrange prisklassen, men det er også hvad jeg generelt kendetegner Fractal-Design for."

"The Mini is a great addition to the product range of Fractal Design, they already had the hugely popular Define R3 and also the huge Define XL for people who need even more space, so it's only logical to address also the mATX-users out there. All the good features that earned the R2 and XL good scores in our reviews are still there in this smaller edition, it's very quiet, looks stylish, comes with affordable price tag and also keeps the components cool enough."

"[Malgré des finitions approximatives,] le Define Mini n’en reste pas moins un bon boîtier pour 90 €, d’autant plus qu’il n’y a pas beaucoup de concurrence sur ce marché des tours microATX."
