Antec 900 E-ATX Big-Tower Case - Black

The Antec 900 supports ATX, E-ATX, SSI-CEB, and SSI-EEB motherboards, including AMD Threadripper systems, and is also compatible with back-connect motherboards for cleaner cable management and improved airflow. The spacious interior accommodates multi-GPU configurations and accelerators like NVIDIA RTX 6000 Ada series GPUs. With support for graphics cards up to 495 mm in length and 160 mm in thickness, the case is designed for the latest generation of high-performance hardware.

Designed for sustained workloads, the Antec 900 offers extensive cooling support with radiators up to 420 mm on the front and 360 mm on the top. The case includes six pre-installed fans and also supports dual 200 mm front fans for high airflow with minimal noise.

The case offers flexible storage options with a total of nine drive bays, supporting up to five 2.5-inch SSDs and four 3.5-inch HDDs, making it ideal for large datasets, project files, RAID configurations, and game libraries.

Inspired by the legacy of the original Nine Hundred case, the Antec 900 continues the philosophy of high airflow and expandability, evolving for modern computing. The open internal layout promotes efficient airflow for stable performance during prolonged workloads such as AI processing, rendering, and simulations.

Constructed from aluminum and steel with a tool-free 4 mm tempered glass side panel, the Antec 900 combines robustness with a clean and professional design, suitable for both workstations and enthusiast builds.
