The Obsidian Series 750D full tower PC case combines generous expansion flexibility, room for advanced cooling options, and an interior that’s optimized for fast and easy builds and upgrades. It has a clean, elegant exterior that dispenses with arbitrary plastic add-ons in exchange for the beauty of brushed aluminum and solid steel. This rigid, rugged exterior surrounds a frame that has ample room for high-performance components and the sophisticated cooling you’ll need if you’re going to push those components to their limits. And, it incorporates a host of clever system builder-focused features, because building a system should be straightforward, trouble-free, and even fun.
Nine PCIe expansion slots support double and triple GPUs. There’s room for up to ten drives, and four USB ports on the brushed aluminum front panel.
The three included Corsair AF140L high-airflow 140mm intake and exhaust fans are custom engineered to deliver excellent airflow with less unnecessary turbulence and noise. You can mount up to eight fans, with room for dual radiators on the bottom, front, and top.
There are four separate mounting locations for the drive cages, and if you’re moving to 100% solid-state, you can remove the 3.5” cages entirely and use the four side-mounted 2.5” cages.
