Summary |
The Antec Nine Hundred was one of the most recognizable high-airflow cases of its time-known for its open design, aggressive cooling, and expandability that let builders push hardware harder than ever before.
The new Antec 900 is a modern interpretation of that legacy.
AI-OPTIMIZED GPU SUPPORT
Built to house multi-GPU / accelerator configurations, including Al-optimized GPUs like NVIDIA RTX 6000 Ada, RTX A6000, and comparable compute cards.
GPU & ACCELERATOR SUPPORT
Designed around professional accelerator cards and full-length, triple-slot GPUs used in AI, compute, and 8K-capable gaming.
SUPPORTS GPUS UP TO 495 MM LONG AND UP TO 160 MM THICK
Spacious interior accommodates multi-accelerator layouts, blower-style compute cards, or mixed GPU + add-in card setups.
