ASCEND to new heights and EXTEND to new depths with the

Mountain Mods Extended Ascension CYO

(Choose Your Own) chassis. This enormous, US-made, hyper-modular case is designed to house the most demanding computing hardware imaginable, offering dimensions of 24x24x18 inches.

Engineered for Extreme Performance and Capacity:

The
Extended Ascension
is built specifically for high-density computing systems, providing the critical space needed for professional applications:

Multi-GPU Powerhouse: The massive interior depth provides ample floor space for extensive multi-GPU configurations required by GPU render farms, professional video editing workstations, and standalone systems for machine learning (Large Language Models). The design ensures superior airflow and heat management for multiple high-end graphics cards operating under sustained load.
Massive Storage Capacity: The extra depth simplifies hard drive integration, with the capacity to hold up to 40 hard drives using optional 120mm HD brackets. This is ideal for large projects, data archives, and enterprise-level storage needs.
Unrivaled Airflow & Compatibility: The open design philosophy ensures maximum thermal efficiency and airflow management. It supports all motherboard form factors (mATX, ATX, EATX, etc.) and provides extensive options for modern cooling solutions and components.
Dual Power Supply Support: This chassis includes options for mounting multiple power supplies (up to 4 optional ports) for systems requiring redundant power or simply extreme wattage.
