## Long description

The CHIEFTEC GM-30B-M-OP (Visio Air platform) is a black cube PC case designed for Micro-ATX and ATX motherboards with a dual-chamber layout and a tempered glass side panel. It combines a brushed-aluminium-style front with a mesh insert and ships with three 140 mm PWM fans (two bottom, one rear) to provide balanced airflow while keeping internal noise low. The internal arrangement supports top and bottom radiators up to 360 mm, motherboard-side 240 mm radiators, CPU air coolers up to 175 mm tall, and graphics cards up to 410 mm in length. The compact dimensions and storage options for 2.5" and 3.5" drives make it suitable for both home and work setups.
Advantages
The cube form factor with a dual-chamber layout simplifies cable management and improves interior visibility through the tempered glass panel. Pre-installed 140 mm PWM fans and a ventilated front panel reduce heat accumulation while maintaining low operating noise. Support for large radiators and long GPUs offers flexibility for performance-oriented builds in a compact footprint.
Suitable for
Micro-ATX and ATX gaming or productivity builds
Systems requiring liquid cooling with up to 360 mm radiators
Compact workstations that need long GPUs (up to 410 mm)
Setups that benefit from tidy cable routing and visible internals
