Compact case with a sleek, minimalist and robust design
The Jonsbo UMX3 Mini Tower case is made entirely of aluminium-magnesium alloy. Its superb design is sleek, minimalist and very robust. Jonsbo's talented engineers used aluminium on the outside and steel on the inside, combined with innovative assembly technology. The result is a case with a solid structure, a sleek aesthetic and exceptional cooling capacity. In fact, for the latter advantage, it is also equipped with hidden cooling channels on the underside.
The third model in the UMX series, the UMX3 is designed for Micro ATX and Mini ATX motherboards. Its main advantage lies in its optimised compatibility with high-end components. Even though the UMX3 has a compact design, it can accommodate graphics cards up to 320 mm in length and, surprisingly, CPU coolers up to 163 mm in height. Well thought out and ingenious, it is compatible with 120 or 140 mm water cooling radiators. What's more, this version with fully transparent acrylic side panels offers an unobstructed view of your components.
