Corsair Obsidian Series 750D Airflow Edition Full Tower ATX Case (Black)


Obsidian Series® 750D Airflow Edition Full Tower ATX Case

The high airflow full tower Obsidian Series case for great-looking high performance PCs

If you’re building a high-performance full tower PC system, Obsidian Series 750D Airflow Edition is a great start.

It combines generous expansion flexibility, excellent air or water cooling capabilities, and an interior optimized for fast and easy builds and upgrades.

The exterior is built from solid steel and brushed aluminum for a clean, elegant look.

Minimalist style, maximum potential

The 750D Airflow 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 fr-ame 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.

High airflow front mesh design

The front panel is what makes the 750D Airflow different than the original 750D. Dual 140mm front intake fans and a low-resistance mesh panel provide quiet, efficient air cooling performance for G.P.Us and D.R.A.M.

Modular drive cage system

The tool-free drive bays can be moved and removed, so you can use only what you need for your particular storage requirements. In turn, you’ll get increased space for components and better airflow potential.

Fast and straightforward builds

Smart design features and an optimized interior make this a true builder’s PC case. That’s because we believe building a system should be straightforward, trouble-free, and even fun.
