Antec has introduced the new 900 full-tower PC chassis, a large and powerful case designed for edge AI computing, professional workstation builds, and high-end gaming systems. The Antec 900 is built to support modern multi-GPU systems, large storage arrays, and demanding workloads that require strong airflow, hardware expandability, and stable thermal performance.
The chassis is aimed at creators, developers, and enthusiasts building rendering systems and workstation PCs designed for AI workloads and machine learning applications. With support for large GPUs, advanced cooling configurations, and multiple motherboard formats, the chassis is designed for modern workstation-class hardware.
The new model follows Antec’s earlier Nine Hundred series, which was known for its airflow-focused design. The updated chassis introduces a modern internal layout designed to accommodate larger GPUs and workstation hardware.
The chassis supports several motherboard sizes, including ATX, E-ATX, SSI-CEB, and SSI-EEB. It also supports AMD Threadripper workstation platforms and newer back-connect motherboards that route cables behind the board. This layout improves cable management and helps maintain unobstructed airflow across high-performance components.
Inside the chassis, the layout supports workstation builds and multi-GPU configurations. The case supports graphics cards up to 495 mm in length and 160 mm in thickness, allowing installation of large gaming GPUs such as the upcoming RTX 5050 GPU with 9GB GDDR7 memory as well as professional accelerator cards for AI development, rendering workloads, and data processing systems.
The case includes six pre-installed fans designed to maintain consistent airflow across CPU, GPU, RAM and storage components. The configuration includes three 140 mm front intake fans, two 120 mm reverse fans mounted on the PSU shroud, and a 140 mm rear exhaust fan to remove hot air from the system.
The chassis also supports large liquid-cooling setups, including up to a 420 mm radiator at the front and a 360 mm radiator on the top. Users who want stronger airflow with lower noise can also install dual 200 mm front fans.
The case provides up to 9 drive bays supporting SSDs and hard drives, useful for systems running high-speed PCIe storage used in AI data centers. This configuration is useful for workstation users handling large datasets, RAID storage arrays, creative production files, and extensive gaming libraries.
The case combines aluminum, steel, plastic, and tempered glass in its construction. A 4 mm tempered-glass side panel allows users to view internal hardware and custom builds while also providing convenient access for upgrades and maintenance.
The design also includes eight expansion slots for add-in cards, multiple fan mounting positions, and dust filters on the front, top, and bottom panels to reduce dust buildup during long-term system use. The front I/O panel includes a USB-C port with 10Gbps transfer speed, two USB 3.0 ports, and a headphone and microphone combo jack.
The Antec 900 full-tower PC case is expected to be available through global retailers and online stores with an estimated price of about $319 USD, €289.99, and £249.99.
