The Obsidian Series: Designed by builders, for builders.
If these are the kinds of questions you’re asking yourself, you need a 900D.
Serious Expansion Flexibility for Serious Builders
- Ten expansion slots

- Four 5.25” optical drive bays

Incredible Cooling Performance and PotentialA cooling-optimized case design requires three things: good passive ventilation, flexible fan mounting options for good airflow, and 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, that’s just the start.
- Includes three AF120L 120mm front intake fans and 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 and easy, without your PC case getting in the way. And, reconfigurations and 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.
You also get modular hard drive cages, and the dust filters and fan covers are easily removable for cleaning and maintenance.
