  • The Hydra 3 is a custom made 4U server case for high throughput density GPU supercomputing solutions, without the unwanted legacy drive bays or back panels. This closed cabinet style server provides a very critical function of active airflow management (using positive pressure, front-to-back) to prevent hot exhaust air from circulating back into the equipment air intake. Full depth design places the motherboard and power supply behind the cards, to give you more space for dual CPU applications. Up to 6 thick server fans can be installed to pull hot air out of the cabinet and ensure cool air actually reaches your cards. The front railing where the GPUs mount can be switched from 8x to 6x mounting holes to give additional space between your cards when only using 6 GPUs. Thick industrial quality steel offers outstanding strength and durability to hold all your cards without flexing for safer storage and transport. This 6U server case is capable of being stacked, rack mounted and holds two power supplies. This mining case requires the use of PCI-E risers to connect the GPUs to the motherboard.

    This is the best enclosure type for high-performance number crunching rigs that generate a ton of heat, without the unwanted air leaks that plague open frame rigs. Server cases are also known to be superb in scalability, as you can rack mount them using industry standard 19" wide rails for high-density applications. A properly constructed server case usually consists of 1.0 mm thick galvanized, cold rolled SECC steel for superior strength, rigidity, and durability.
