Spacious Interior for High-End Builds
Despite its compact footprint, the ASUS PRIME AP303 TG White can house full-size ATX motherboards and long graphics cards up to 360 mm. The interior layout keeps cabling tidy with dedicated routing channels and tie-off points, helping maintain clean airflow. Builders can install up to three 120/140 mm fans on top and one 120 mm fan at the rear for balanced cooling performance.
Premium Cooling and Radiator Options
Cooling flexibility is a standout feature. The top panel supports radiators up to 360 mm in length and 60 mm in thickness, ideal for liquid cooling loops. A 120 mm rear exhaust fan is pre-installed, and the case includes dust filters on the top and bottom to keep components clean. This makes it suitable for both air and liquid cooling setups without compromising on noise or thermal efficiency.
Tempered Glass and Clean Aesthetics
The side panel is made from tempered glass, offering a clear view of internal components and RGB lighting. The white finish and clean lines suit modern build themes, while the PSU shroud hides cables and the power supply for a professional appearance. The front panel’s USB 3.2 Gen 2×2 Type-C port ensures fast data transfer for external devices.
