Hydra I 8 GPU Mid Tower Case

The Hydra 1 is a custom made mid-tower case for high density GPU mining using 8 cards. This case supports eight full-length graphics cards, one ATX/Micro-ATX motherboard, and two power supplies for better power distribution. If you want to use this case as a bench or test bed, it is great for that too with an open-air chassis design that lets you get in and swap cards easily. There are two aluminum handles on top so you can just grab and go. Thick industrial quality steel offers outstanding strength and durability to hold all your cards without flexing for safer storage and transport. The motherboard is mounted behind the case with 85 mm of clearance for CPU coolers. Extended distance from MoBo to GPU allows optimal placement of your cards. You can install 3 x 120mm high RPM fans that blow hot air out of the case from bottom to top.

This case is a great compromise between the heavy-duty server cabinet solutions and light-duty open frames. It provides high structural rigidity and quick access to components.
