ASUS A21 PLUS TG White Case

ASUS A21 PLUS TG White is a compact Middle Tower case aimed at cleaner and tighter Mini ITX and Micro ATX builds. The white chassis with tempered glass allows you to showcase your hardware without sacrificing airflow and space for components. Inside, there is room for a graphics card up to 380 mm and a CPU cooler up to 165 mm, which opens options for more serious gaming configurations. The included 4 fans save you additional costs and time in choosing cooling solutions.

What you get

With support for Mini ITX and Micro ATX motherboards, the case is ideal for a compact yet not overly restricted system, with enough space for a powerful GPU and normal airflow. The configuration of fans on the top, front, and rear panels allows you to create meaningful airflow – front for intake, top and back for exhausting warm air. With a maximum of 380 mm for the graphics card, most modern long GPU models fit comfortably, while the limitation of 210 mm for the power supply is OK for standard ATX PSUs, as long as you don’t overdo it with long cables and additional cages. The combined 2.5"/3.5" slots give you flexibility – you can place either a larger HDD for storage or more SSDs as needed. The tempered glass is more durable than regular plastic and provides a clean view of the components and cable management.

• Case form factor Middle Tower with support for Mini ITX and Micro ATX motherboards – a good balance between compactness and upgrade options.
• Maximum graphics card length up to 380 mm, allowing installation of most modern, longer gaming GPU models.
• Supported CPU coolers up to 165 mm, so you can install a serious air cooler, not just a low stock variant.
• Overall 4 included fans, providing basic, ready cooling right out of the box, without needing to buy additional fans.
• Rich airflow options: front panel 3 x 120 / 2 x 140 mm, top panel 3 x 120 / 2 x 140 mm, and rear panel 1 x 120 mm for effectively expelling warm air.
• Side panel made of tempered glass, showcasing the hardware and RGB, while being more durable than regular glass.
• Practical storage options with 1 x 2.5" and 2 x 2.5"/3.5" Combo Bay, suitable for a combination of SSD for the system and HDD for large data volumes.
• Support for power supplies up to 210 mm (without built-in PSU), allowing you to choose a standard ATX power supply with sufficient power for your configuration.
• Convenient front I/O ports – 2 x USB 3.2 Gen 1 and 1 x HD Audio for easy access to peripherals and headphones.

Who it is suitable for

ASUS A21 PLUS TG White is well-targeted at gamers and enthusiasts who want a compact, white system with a transparent side panel and space for a serious GPU. It is suitable for 1080p and 1440p gaming builds, as well as for tighter workstations where you don’t need a huge ATX case. If you plan on an E-ATX motherboard or extreme water systems with many radiators, the form factor and internal volume may feel limited.

The combination of tempered glass, included four fans, good support for long graphics cards, and standard ATX power supplies makes ASUS A21 PLUS TG White a very reasonable base for a clean, organized, and modern build.
