The QUBE 340 supports Mini-ITX and Micro-ATX motherboards and offers up to 366 mm space for graphics cards if no fan is mounted at the front. CPU coolers can be up to 178 mm tall. This allows powerful hardware for gaming and demanding applications to be housed even in a compact system.
Flexible cooling with up to six fans
Two 120 mm or 140 mm fans can be mounted at the front and on the top panel respectively. Additional fans can be installed at the rear and bottom. Furthermore, the case supports 240 mm radiators at the front and top, allowing you to choose between strong air cooling and a compact water cooling solution.
Adapts to your setup
The case can be positioned horizontally or vertically, and the I/O panel can be placed at the top or bottom. This keeps USB-C, two USB-A ports, and the headset jack conveniently accessible depending on the location. Behind the motherboard, there is also 30 mm of space for cable management to keep the interior tidy.
