ANTEC 900 — A Full-Tower Chassis for Edge AI, Workstations, and 8K Gaming

The original Antec Nine Hundred stood out as a highly recognizable, open-design high-airflow chassis that offered aggressive cooling and broad expandability, enabling builders to drive their components further than before. This updated Antec 900 serves as a contemporary reinterpretation of that established heritage.

Engineered to accommodate ATX, E-ATX, SSI-CEB, SSI-EEB motherboard form factors, alongside AMD Threadripper processors.

Constructed to house multi-GPU and accelerator arrangements, incorporating AI-focused graphics cards such as the NVIDIA RTX 6000 Ada, RTX A6000, and equivalent compute hardware.

Engineered specifically around professional accelerator hardware and full-length, triple-slot graphics cards utilized within artificial intelligence workloads, heavy computing, and 8K gaming setups.

Accommodates GPUs measuring up to 495 mm in length and up to 160 mm in thickness. The roomy interior easily supports multi-accelerator layouts, blower-style compute hardware, or mixed configurations combining graphics cards with add-in expansion cards.

The '900' designation directly reflects its storage adaptability. Equipped with 9 total drive bays, this chassis is redesigned to handle large AI datasets, scratch disks, media project libraries, and RAID arrays.

Features 5 x 2.5" and 4 x 3.5" drive bays, with convertible options available to support additional 2.5" drives.

Incorporates an ultra-case structural architecture designed for superior ventilation, resulting in significantly enhanced cooling performance for your graphics cards.

Featuring 6 pre-installed high-performance fans, the 900 enhances its airflow architecture to provide significantly more consistent and advanced cooling efficiency.

Includes 3 TQ140 high-performance 140mm intake fans positioned at the front, 2 PI2R reverse-flow 120mm fans located on the power supply shroud to regulate internal chamber airflow, and 1 TQ140 140mm exhaust fan at the rear.

Accommodates 2 front-mounted 200mm intake fans, enabling high-volume, low-RPM airflow tailored for quiet operation environments.

Radiator Support: Front accommodates up to 420mm (under 52mm thickness). Top accommodates up to 360mm (under 52mm thickness).

Features a high-speed USB Type-C 10Gbps port for fast external connections.

Route cables smoothly from the rear to achieve a pristine front aesthetic and improve internal airflow efficiency.

Includes 8 expansion slots that offer ample space for accelerators, high-speed networking gear, capture cards, and storage controllers.

Designed with a 4 mm tempered-glass side panel that allows fast, tool-free entry to internal components.

Simplify installation by mounting your fans or radiators directly onto the cooling bracket before securing the entire assembly back into the chassis.

Keeps your system clean with magnetic dust filters located on the top and front, complemented by a full-sized pull-out dust filter at the bottom.

Engineered to deliver an unobstructed and clean cable routing experience throughout the build.

Accommodates ATX, E-ATX, SS-CEB, SSI-EEB, and Threadripper motherboards alongside Back-Connect support. Features a maximum CPU cooler height of ≤ 190 mm, a maximum GPU length of ≤ 495 mm (465mm with front fans installed), a max GPU thickness of 160mm, and supports power supplies up to ≤230mm or ≤170mm with side mounting.
