## Long description

The Chieftec AS-02B-OP Midi Tower Black is a PC case designed to accommodate Mini-ITX, Micro ATX and ATX motherboards while maintaining a compact footprint. The case measures 215 mm wide, 390 mm deep and 485 mm high, and ships with one pre-installed 120 mm rear fan. The exterior features a black finish and front panel support for fan or radiator configurations in diameters of 120 mm, 140 mm, 240 mm, 280 mm and 360 mm, enabling varied cooling setups for system builds.
Advantages
The chassis offers a balance of size and expandability suitable for mid-sized builds, with dedicated mounting locations for two 3.5" drives and two 2.5" drives. Front I/O includes two USB 2.0 ports for basic peripheral connectivity. The pre-installed 120 mm rear fan assists exhaust airflow out of the case while additional front fan or radiator options allow for more intensive cooling arrangements. The case’s support for standard ATX and smaller motherboards ensures compatibility with a wide range of components.
Suitable for
Building a mainstream gaming PC using ATX, Micro ATX or Mini-ITX components

How to use
Install a compatible motherboard (Mini-ITX, Micro ATX or ATX) onto the motherboard tray using the supplied standoffs. Mount storage devices into the designated 3.5" and 2.5" bays and route power and data cables through the available openings. Fit the power supply into the PSU area (power supply not included) and connect necessary power lines. Configure cooling by installing front fans or a front radiator in supported sizes and ensure the pre-installed 120 mm rear fan is connected for exhaust airflow. Secure expansion cards and close the side panels before powering on the system.
Usage recommendations
For effective cooling, pair the included rear 120 mm fan with at least one front intake fan or a front-mounted radiator. Use cable routing and the provided drive mounting locations to maintain unobstructed airflow. Verify clearance for long GPUs and tall CPU coolers against the case depth and internal layout prior to final assembly.
