The CM 690 III ships in a large box with a clear image of the case on the front. The back of the box features a list of key features. Inside, the CM 690 III is protected by layers of Styrofoam.

At a glance it is easy to mistake the CM 690 III for the CM 690 II.

The biggest change to the exterior can be seen on the side panel. Whereas the CM 690 II uses two mesh cut-outs the CM 690 III features a single, larger mesh.

The front panel is identical to that of the CM 690 II with four 5.25″ drive bays and a large mesh covering the included front in-take fan. The CM 690 II's concave front panel design has been changed to reflect a more convex design. Although the change is minor, it does give the overall design of the case a more rounded look.

Other changes are not as easily spotted, so let's move in closer to see what else the CM 690 III has in store.

The I/O panel offers quick access to two USB 3.0 ports, Audio and Mic jacks, two USB 2.0 ports, the Power button and Reset button. The CM 690 III uses square Power and Reset buttons instead of the round buttons found on the CM 690 II.

The top panel compartment makes a return. However, Cooler Master have chosen to remove the external SATA and power connectors found on the CM 690 II. Instead, the compartment now serves to store personal belongings. The plastic cover hides the I/O panel from view.

White LEDs light up and are visible through the plastic cover whenever the system is turned on.

Around the back of the case we can see the top panel has changed subtly as well. The relief found on the CM 690 II has now been replaced with a smooth, even mesh. The top panel is held in place with a single thumbscrew and can be removed easily.

Flipping the CM 690 III on its side reveals a large dust filter underneath the power supply.
