Chieftec VISIO AIR GM-30B-M-OP is a black, dual-chamber PC case for building a desktop system. Its tempered-glass side panel and front panel of brushed aluminum and mesh define its exterior. It supports Mini-ITX, Micro-ATX and ATX motherboards, including back-connect designs.
Inside are two 2.5-inch bays and two 3.5-inch bays. An ATX power supply is installed separately. Three 140 mm PWM fans are pre-installed, with two at the bottom and one at the rear. Front I/O includes one USB 3.2 Gen 2 Type-C port, two USB 3.0 ports, audio-out and microphone-in for connecting peripherals.
The case measures 430 × 295 × 390 mm and accommodates CPU coolers up to 175 mm high and graphics cards up to 410 mm long. Radiators up to 360 mm fit at the top or bottom, while the motherboard side supports up to 240 mm. These clearances help when planning a desktop build with air or liquid cooling.
