** The Obsidian Series: Designed by builders, for builders.** Obsidian Series 900D is for serious builders with big projects. Do you want to design your ultimate dream PC? Add state-of-the-art liquid cooling or air cooling? Build a quadruple GPU, dual CPU graphics powerhouse? Or, just create a monster file server? If these are the kinds of questions youre asking yourself, you need a 900D. ** Serious Expansion Flexibility for Serious Builders** We dont need to tell you that theres no such thing as too much room. Well just let the numbers speak for themselves:
- Ten expansion slots
- Fits up to nine hard drives or SSDs, with three hot-swap mounts
- Four 5.25" optical drive bays
- Room for dual power supplies & if nine hard drives or SSDs arent enough, you can expand to 15 drives by adding additional drive cages (available separately). ** Incredible Cooling Performance & Potential** A cooling-optimized case design requires three things: good passive ventilation, flexible fan mounting options for good airflow, & the room to add sophisticated active cooling systems. The Obsidian Series 900D starts with a clear airflow path from the intake fans to the case interior, with no drives in the way. But, thats just the start.

Includes:: three AF120L 120mm front intake fans & one AF140L 140mm rear exhaust fan
- 15 total fan mount locations
- Five radiator mounting points
- Four removable dust filters ** Easy to Build With. Easy to Live With.** System builds should be straightforward & easy, without your PC case getting in the way. &, reconfigurations & upgrades should be just as simple. An enjoyable build process with great-looking results is a huge part of the pride of ownership that comes with building high-performance PCs. The 900D can help make it all happen with tool-free side panel access, hard drive installation, & optical drive installation. Inside, youll find a CPU backplate cutout & rubber grommets on
