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.

STORAGE &
DATA READINESS
The "900" isn't just a name-it's built in. The 9 total drive bays nod directly to the original's storage flexibility, now reimagined for Al datasets, scratch disks, project libraries, and RAID.

UP TO 9 TOTAL DRIVE BAYS
5 x 2.5" and 4 3.5" (or convertible for more 2.5" )

POWERFUL AIRFLOW PATH DESIGN
ultra case structure design for excellent airflow,delivering enhanced GPU cooling performance.

INCLUDED FANS FOR ENHANCED COOLING PERFORMANCE
Equipped with 6 high-performance pre-installed fans, the 900 further optimizes its airflow design to deliver more stable and superior overall cooling efficiency.

SERIOUS COOLING HEADROOM
Radiator Support: Front up to 420 mm (<52 mm thickness). Top up to 360 mm (<52 mm thickness).
