CTE C750 Air PC Case

The CTE C750 Air was designed for systems where cooling performance, clean layout, and flexible expandability are priorities. With its clear structure, innovative cooling concept, and generous space, the case is especially suitable for performance-oriented builds that require plenty of room for radiators, high-performance GPUs, and storage devices.

CTE architecture for optimized airflow

The heart of the case is the CTE architecture (Centralized Thermal Efficiency), where the motherboard is installed rotated by 90 degrees. This rotation brings CPU and GPU closer to their respective air sources, which better distributes heat generation and allows more targeted fresh air supply. The central thermal separation improves cooling performance for both air and water cooling without compromising component space. The clear airflow not only increases cooling performance but also reduces thermal interference zones within the system.

Three CT140 fans pre-installed

For effective basic ventilation, three 140mm CT140 fans are already integrated into the case – at the front, top, and rear. These fans spin at up to 1,500 RPM with a maximum noise level of 30.5 dBA and generate a static pressure of 3.02 mm-H₂O at an airflow of 84.32 CFM. Additionally, numerous other fans can be installed – up to a total of 14 units, distributed across the front, top, rear, motherboard tray, PSU cover, and bottom area. For users who rely on water cooling, there is the option to accommodate radiators up to 420 mm in size at various locations, such as on top, rear, or side.

Compatibility for high-performance hardware

Inside, there is space for motherboards up to E-ATX size (12 × 13 inches). The maximum GPU length is 420 mm, allowing installation of even particularly long graphics cards. For air coolers, there is up to 190 mm of clearance. The Power Supply can be up to 220 mm long and is housed in a fully shielded Power Supply chamber. This separation simplifies cable management, improves airflow, and enhances the system's structural design.

Expandable drive system

The case offers extensive options for integrating storage media. It is possible to install up to seven 3.5-inch HDDs or alternatively up to twelve 2.5-inch SSDs, depending on the combination and arrangement of the carriers. This makes the CTE C750 Air suitable both for high-performance systems with fast SSD storage and for large amounts of data on mechanical hard drives. The modular design makes modifications and upgrades easier when needed.

Tempered glass side panel and mesh grille on the front

A key visual feature is the generous 4mm thick tempered glass side panel, which provides a clear view of the system's interior. Ideal for RGB-focused builds or premium component showcases. The front is equipped with a large mesh grille that ensures high airflow while also serving as a dust barrier—functional and cleanly designed for maximum cooling performance.

Comprehensive dust protection

Fine mesh dust filters are integrated at all critical openings of the case. These are located at the front, top, bottom, rear, and right side opening. All filter elements are removable and can be cleaned without tools, which greatly simplifies system maintenance and ensures permanently clean air channels.

Variety of connections on the I/O panel

For modern connectivity, the case is equipped with a comprehensive I/O panel on the top. It offers four USB 3.0 ports, one USB 3.2 Gen 2 Type-C port, and audio jacks for headphones and microphone. The positioning is ergonomically chosen so that connected devices like headsets, external drives, or controllers remain easily accessible—even when the case is placed on the floor.
