Cooler Master CM 690 III Case Review

IMG_8604
The front panel is held in place with 6 clips and can be removed easily. With the front panel out of the way we can see the large 200 mm front in-take fan. Alternatively, users can install either two 120 mm, two 140 mm fans or a single 180 mm fan.

Without fans or a radiator in the top users can quickly access the motherboard. That said, the large roof spaces allows for the installation of two 120 mm fans, two 140 mm fans or a single 200 mm fan. Alternatively, a 240 mm radiator, such as the Cooler Master Seidon 240M or Eisberg 240L Prestige can be installed with ease.

Turning to the inside of the case and starting at the bottom left, we can see there are four rubber feet to reduce vibrations from the power supply.

Interestingly, the expansion slot covers are held in place with normal screws, rather than thumb screws. Cooler Master also include a 120 mm rear exhaust fan with the CM 690 III.

A large CPU cut-out facilitates the installation of CPU coolers without removing the motherboard. Directly below the CPU cut-out are four mounting holes. These can be used to mount a Solid State Drive behind the motherboard tray.

Along the center of the case are four cut-outs to aid with cable management. Avoiding the use of rubber grommets, they have taken extra care to ensure there are no rough edges.

In the bottom right corner of the case are three 3.5″ drive bays. Directly above these are four 2.5″ drive bays. Both drive cages are fully modular and can be removed completely to allow for the installation of a 240 mm radiator in the front.

Finally, a total of three 5.25″ drives can be installed and secured with a plastic locking mechanism.

The included 120 mm rear exhaust fan sits directly above three rubber grommets.

Changing our angle gives us a better view of the drive cages in the front. Dubbed EZ trays, the drive caddies can extend and retract to support both 2.5″ and 3.5″ drives.

Around the back we can see Cooler Master have included a healthy number of cable tie points. Users who do not have access to angled SATA connectors will be happy to see there is plenty of space behind the drive cages.

As we mentioned above, the drive caddies support both 2.5″ and 3.5″ drives. Users can opt to secure 2.5″ drives with drives or by retracting the sides of the caddie.

As always, we aim to find out how forgiving a case is by stacking cables cable deliberately and only applying minimal cable management. The convex design of the CM 690 III's side panel means even the thickest cables will not pose a problem.

Overall, building into the CM 690 III was a breeze and we did not run into any issues.
