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.

KitGuru says: Which model of the new InWin Covalent do you like the most?

The post InWin unveils modular Covalent full-tower with back-connect motherboard support first appeared on KitGuru.

InWin Development Inc. has introduced a new full tower PC case called the InWin COVALENT. This case is made for users who need high performance, such as AI work, heavy computing, and professional workstation builds. It focuses on strong cooling, large space, and a clean design.

The InWin COVALENT comes in two side panel options. One version has tempered glass, which lets users see inside the build and show RGB lighting. The other version uses solid metal panels, giving a more simple look while also improving strength and airflow. The front panel has a vertical slot design that helps bring more air inside, keeping temperatures under control during long usage.

This InWin COVALENT case is built for serious hardware. It supports large motherboard sizes like EEB, which are often used in workstation systems. There is enough space inside for multiple high-end graphics cards and storage drives without blocking airflow. The case includes eight PCIe slots, allowing both horizontal and vertical GPU installation. A strong steel frame and optional GPU support help keep everything stable over time.

Cooling is one of the main highlights. The COVALENT can support up to two 420 mm radiators and up to 13 fans. It already comes with four pre-installed fans, giving good airflow out of the box. This makes it suitable for heavy workloads like AI tasks or multi-GPU setups where heat can be a problem.

The inside layout is modular, so users can adjust it based on their needs. It supports both 3.5-inch and 2.5-inch drives, with extra options available through add-ons. Other useful features include a separate power supply chamber, tool-free panels, a front USB Type-C port, and a built-in fan hub for easier cable management.

InWin COVALENT specifications

Overall, the InWin COVALENT is clearly made for users who need space, cooling, and flexibility in one case. It targets high-end systems and offers features that support long-term and heavy use.
