ASUS PRIME AP303 TG Compact ATX Case Black

ASUS PRIME AP303 TG is a compact Middle Tower case aimed at mid-range configurations where you want a good balance between size, airflow, and visual cleanliness. It supports ATX, Micro ATX, and Mini ITX motherboards, giving you the freedom to choose your platform and future upgrades. The tempered glass showcases the configuration without looking gaudy, especially if you combine it with discrete cooling and organized cable management. The space for the graphics card up to 360 mm and cooler up to 165 mm gives you peace of mind for most modern GPUs and more serious CPU air coolers.

What you get is a chassis designed for real use – from the front-mounted power supply to the I/O panel and cooling options. With the ability to support up to 3 x 120/140 mm fans on the top panel plus 1 x 120 mm at the back, you can create a meaningful front-to-top/rear airflow, especially with hotter GPUs. One fan is included, which is a good start, but a configuration for serious gaming will want at least another 1–2. The internal storage configuration with 2 x 2.5" and the option for 1 x 3.5" or another 1 x 2.5" covers a typical setup: SSD for the system and games plus an additional SSD/HDD for data. The I/O panel with 2 x USB 3.2 Gen 1 and HD Audio gives you convenient access for headphones, flash drives, and external drives without stretching to the back of the case.

• A case in the Middle Tower form factor that combines a more compact size with full support for ATX motherboards.
• Support for motherboards ATX, Micro ATX, and Mini ITX, which leaves you a wide choice for build and upgrade.
• Tempered glass on the panel that showcases the hardware and RGB without sacrificing strength and sound insulation like regular acrylic.
• Ability to support up to 3 x 120/140 mm fans on the top panel and 1 x 120 mm at the back, allowing you to build adequate airflow for more powerful configurations.
• Maximum graphics card length of 360 mm, allowing installation of most modern high-performance GPUs without compromise.
• Support for CPU coolers up to 165 mm in height, sufficient for serious tower coolers from mid and upper mid-range.
• Flexible storage: 2 x 2.5" slots plus 1 x 3.5" or an additional 1 x 2.5", suitable for a combination of SSD and HDD according to your needs.
• 7 expansion slots that cover a classic ATX configuration with a GPU and additional cards if needed.
• Front-mounted power supply with support for PSU up to 180 mm in length, giving you the choice between more compact and more powerful power supplies.
• Front I/O with 2 x USB 3.2 Gen 1 and HD Audio for quick access to peripherals and audio devices.

This case is suitable for someone who wants a neat, modern ATX or mATX build – primarily gaming or multimedia, without monstrous custom water cooling. If you are chasing huge amounts of drives or legacy devices, the lack of 5.25" and limited 3.5" slots may be a downside. But for a typical modern gaming or work configuration with 1–2 SSDs and possibly one HDD, it is completely sufficient.

The combination of compact dimensions, decent internal capacity, and tempered glass makes ASUS PRIME AP303 TG a logical choice if you are looking for a practical yet visually clean foundation for your next build. The fact that it accommodates long GPUs and taller air coolers without going into a huge Full Tower is particularly strong.
