InWin unveils modular Covalent full-tower with back-connect motherboard support

InWin has announced the Covalent, a flagship full-tower case designed for high-performance computing (HPC), AI development, and professional workstations. The case features a modular internal architecture and a refined industrial aesthetic, offering a choice between tempered glass or solid metal side panels.

The Covalent is designed to accommodate workstation-class hardware, providing native support for EEB (12″ x 13″) and E-ATX motherboards. Notably, the case is compatible with “back-connect” (BTF) motherboard designs, which move cable headers to the rear of the PCB for a cleaner interior. The spacious interior supports graphics cards up to 480mm in length and CPU heatsinks up to 190mm tall. With eight PCIe expansion slots, users can install multiple GPUs in either horizontal or vertical orientations, and InWin includes optional GPU support brackets to prevent card sag.

Thermal performance is a primary focus for the Covalent, as it supports up to 13 fans (140mm or 120mm) and can house dual 420mm radiators simultaneously on the top and side panels. For out-of-the-box airflow, the case comes pre-installed with four CV140 fans, three in the front and one in the rear. The front panel utilises a vertically slotted design to maximise intake, while a dedicated PSU chamber helps isolate the heat from the rest of the system. An integrated fan hub supports up to six PWM and ARGB connections, simplifying cable management.

Storage and connectivity are generous, with a modular layout that can hold up to eight 3.5-inch drives or nine 2.5-inch drives via optional brackets. The front I/O panel includes one USB-C 3.2 Gen 2×2 port, two USB 3.2 Gen 1 ports, and two USB 2.0 ports, along with a standard HD audio jack. To assist with assembly and maintenance, InWin has implemented tool-free side panels and a removable dust filter system. The tempered glass model is priced at €149.99, while the metal version retails for €144.99.
