ASUS ASUS A31 Tempered Glass ATX Mid-Tower Computer Case

The ASUS A31 TG BLACK is a mid tower computer case that puts your build on display through a front panel made from tempered glass and a matching side panel. Whether you are assembling a gaming rig or a showpiece workstation, the clear panels let you highlight lighting effects, custom cooling loops, and carefully chosen components without distraction.

Inside, the chassis accepts ATX, microATX, Mini-ITX, and back-connect BTF motherboards, so you have room to choose a board that matches your needs and budget. Two bays accommodate either 2.5-inch or 3.5-inch drives, while seven expansion slots leave space for graphics cards, capture cards, or other add-in hardware. The layout is straightforward, making component installation and upgrades feel familiar even if you build only once in a while.

Cooling flexibility is a core part of the design. The top panel can mount up to three 120 mm fans or two 140 mm fans, and it also supports a radiator up to 360 mm in length for builders who prefer liquid cooling. A rear slot handles one additional 120 mm or 140 mm fan to create balanced airflow from front to back. Removable dust filters on the top and bottom help keep the interior clean and maintain airflow over time.

Behind the motherboard tray, 34 mm of cable routing space allows you to tuck away power and data lines so they stay out of sight when viewed through the glass panels. On the front I/O panel, a USB 3.2 Gen 2x2 Type-C port delivers high-speed access for external drives, while two USB 3.2 Gen 1 ports handle everyday peripherals. A combined audio jack keeps headset connections within easy reach, making this case a practical choice for desks that sit against a wall or in a home office.

Whether you are building your first PC or refreshing an existing setup, the A31 TG BLACK offers a clean style, sensible cable management, and expansion options that grow alongside your hardware.
