Today we have the chance to look at a new and sexy all aluminum chassis from Cooler Master, the Mystique 631. This product has recently taken on a new name. It was previously known as the Wave Master II and our review sample is still carrying the original name. As with all the products we have looked at from Cooler Master their packaging is top notch, pretty much assuring a safe trip from the warehouse to our front door.

The images above show the packaging and additional hardware that comes with the Mystique The 5 1/4” and 3 1/2” drive bays are completely tool free which means adding and removing optical and floppy drives is a breeze.

The Exterior

This chassis falls into the Mid Tower class and includes 4, 5.25” drive bays and 2, 3 ½” bays. As the 3 images above show us, the Mystique is a very elegant looking chassis. Since the case is made of aluminum it is extremely lightweight when compared to a rigid steel chassis.

The first feature that caught our eye was the ability to remove the front door and reverse it to open from the left as opposed to opening from the right as it does out of the box.

This feature changes the appearance of the chassis as well as giving it some additional flexibility when it comes to finding the proper place for our fully assembled system to sit.

The first image to the left shows the side panel that has the air intake on the lower left. It sits underneath the air duct that directs air towards the CPU. This panel also has the release handle that enables us to remove the side panel. The next image shows us a close up view of the air duct that is on the inside of the side panel.

The rear side panel has nothing fancy to note, but it maintains the clean appearance of the Mystique. Next we have a look at the rear of our chassis. The layout is very common other than the additional holes that have been pre drilled to accommodate liquid cooling setups. The ability to add liquid cooling without having to chop up a case is a nice touch that we will look closer at in an upcoming review.

On the top of the chassis there are two USB ports, a fire wire port and mini-pin jacks for a set of headphones and a microphone.

The 2 images above look at the interior of the front panel. The panel has a mesh grill as well as a removable mesh filter that can be removed and cleaned. The grey plastic frame then clips into place to hold things in place.
