Final Thoughts and Conclusions

The Obsidian Series 750D is the third new Obsidian case to be introduced by Corsair in 2013. It shares many of the same design elements present on Corsair’s popular Obsidian 350D micro-ATX chassis and the 900D Super-Tower. The new 750D offers more room, better cooling, and more drive location options than Corsair’s popular 650D enclosure, at a lower price.

The Obsidian 750D case can easily accommodate oversized motherboards and extended VGA adapters and offers six internal 3.5” HDD/SSD mounting trays, four internal 2.5” SSD trays, and three external 5.25” bays but does not have any built in 3.5”/2.5” HDD hot-swap options.

Case cooling is very good right out of the box thanks to the three included 140mm fans configured to provide positive case air pressure.  Three easily removable air filters help keep the dust out. And if you want to go with liquid cooling the 750D can accommodate just about anything you might plan to use; with four different radiator mounting locations supporting single, dual or triple fan combinations.

Overall the build quality is very good, the case is easy to work with, and it provides very good cooling in the base configuration with the three included 140mm fans. If you are looking for a high-end case with great looks and a little more room than a typical mid-tower enclosure has to offer, then the new Obsidian 750D might just be what you are looking for.
