The Chieftec Visio Air GM-30B-M-OP is a black dual-chamber computer case designed to keep your workspace tidy by hiding the power supply and drives behind the motherboard. Its construction combines 0.65-0.9mm SPCC steel with a tempered glass side panel and a front panel made of brushed aluminum and mesh, providing a clear view of your components while maintaining steady airflow. Measuring 430mm x 295mm x 390mm and weighing 6.8 kg, it supports Mini ITX, mATX, and ATX motherboards, including specialized ASUS BTF and MSI Project Zero models with rear connectors for a cleaner internal look. Cooling is a priority in this chassis, which comes with three pre-installed 140mm PWM fans located at the bottom and rear. You have extensive options for expansion, with the ability to mount radiators up to 360mm on both the top and bottom, and a 240mm radiator on the motherboard side. The interior is spacious enough to accommodate a VGA card up to 410mm long and a CPU cooler height of 175mm. For storage and power, it includes two 2.5" and two 3.5" internal drive bays and supports ATX power supplies up to approximately 200mm in length. Connecting your peripherals is straightforward via the front I/O panel, which features a USB 3.2 Gen2 Type-C port, two USB 3.0 ports, and dedicated audio and microphone jacks. With six expansion slots and a thoughtful layout, this case is well-suited for enthusiasts building a high-performance system who want a compact footprint without sacrificing the ability to use full-sized components.
