Detailed Exterior Features

Now that the basic exterior features have been perused, it's time that we take a more detailed look at the Cooler Master ATCS 840. First and foremost, I must warn you that the RC-840 computer case is far larger in your hands than the images below depict. The ACTS 840 measures 9.57" wide by 22.83" tall, and has a depth of 24.80" for 5418 cubic inches of total chassis footprint. While the aluminum alloy panels might do their part to reduce the overall product weight, the RC-840 still weighs 29.21 pounds completely empty. Add your motherboard, expansion cards, and drives, and this computer case will likely see 40 lbs with ease.

It's not expected that mobile gamers will tote the ATCS 840 to a local LAN party, as there are plenty of better alternatives for the task. The RC-840-KKN1-GP is really intended for performance enthusiasts who work inside their computer case quite often. Follow along, and you'll soon find out why.

Cooler Master has disguised the front bezel trim plate as a dust shield for the 230 x 30mm cooling fan hiding behind it. The front intake cooling fan is removable from the inside, but the dust trap is easily cleaned from the outside of the case.

Atop the RC-840 is a retracting I/O panel that rests flush with the top portion of the ATCS and rotates upward with a push on the module. Cooler Master has loaded the ATCS 840 with four additional USB 2.0 ports, an audio input and output lead, IEEE-1324 Firewire, and an eSATA 1.5 Gbps port.

Directly in front of the I/O panel is the power and reset buttons, with two small LEDs indicating system status and data access. All of these connections (including the additional I/O ports) must tie into the motherboard for functionality, so ensure that your hardware will support the additional ports.

The ATCS 840 is much taller than most enthusiasts will require of their computer case. Even though many overclockers and hardware enthusiasts appreciate the extra room of a full-tower design, having six total 5.25" expansion bays is more than the status quo. The upside, however, is the lack of an irritating bezel door. It's about time manufacturers drifted away from the classic designs which often-times included a locking bezel door.

Because of the weight, Cooler Master decided to fit their flagship ATCS 840 computer case with stylish round home theater-style feet. A rubber insert keeps vibration to a minimum, although I suspect even an empty version of the RC-840 would be immune to these problems.

Pictured in the image above, you can see how Cooler Master has given the ATCS 840 both a PSU fan intake, along with a filtered bottom fan for this computer case. The PSU actually does have a filter unit, but it's accessible from the inside of the RC-840.

In our next section, we skim over some of the general details inside the Cooler Master RC-840-KKN1-GP full-tower computer case.
