Corsair ship the Obsidian 750D in a large brown box with some key features listed on the front. Inside, the case is protected by layers of styrofoam.
Directly below the front panel connectors and buttons are the covers for the three 5.25″ drive bays. Below that is a large brushed aluminium panel. Moving in closer gives us a better look at the brushed finish. The markings on the corners of the panel indicate where to press to remove the panel.
The front panel houses two USB 3.0 ports, two USB 2.0 ports, audio and mic jacks, a reset button and a large power button in the middle. On the left-hand side we can see the large windowed panel and on top we find a magnetic dust filter.
Turning the case around shows how big the window really is. Corsair fans will be happy to see masking tape is still used to hold the front panel in place while a thin film protects the window during transport.
A close-up of the Power button shows Corsair has extended the brushed aluminium look to every aspect of the front. The LEDs, serving as HDD Activity indicators, light up in a soft white tone that does not distract.
The rear exhaust fan is the only visible pre-installed fan. Directly above the fan is a mesh that covers the side of a radiator, if one is installed, or any fans that builders install as top exhausts.
Builders using a 140 mm AIO cooler, such as the Corsair H90, can also remove the rear exhaust fan to mount the cooler.
A total of 9 expansion slots and a standard power supply cut-out round out the back of the case.
Finally, we find a removable dust filter underneath the power supply. This dust filter slides out smoothly and is secured firmly once it is put back in place.
