PRODUCT PICTORIAL AND WALKTHROUGH
The bottom of the case has two ventilation areas, one for the PSU intake and one for an optional 120mm intake fan. Removable, washable filter screens are featured for both, and audio cabinet style feet allow ample air circulation under the chassis. This is an excellent design that's well executed and other manufacturers should take a cue here.
After removing two thumbscrews, the side panel comes off to reveal the roomy interior. A paper template comes pre-installed on the motherboard tray to aid the user in placing the motherboard standoffs, and is held in place with several pieces of tape for easy removal. While the chassis is predominately aluminum, some of the structural bracing is steel, giving the 840 a robust quality not seen in some other aluminum chassis'.
Here's a shot of the top exhaust fans. These big boys turn at a leisurely 700 RPM and are rated at less than 20dBA for whisper quiet operation. In this photo we can also see the extensive bracing that keeps this aluminum chassis very stiff and rigid, even with the side panels off.
This photo of the floor shows the PSU filter and optional fan placement seen earlier. The PSU filter is large enough and correctly placed to do its job, longer power supplies may make filter cleaning a chore. However, I still like this design better than any I've seen so far.
The entire front of the 840 is dedicated to drive cages. With room for six 5.25” devices and six HDDs, the 840 will be sufficient for the vast majority of enthusiasts. Another 230 X 30mm fan (with similar specs as the top fans) pulls intake duties in front of the HDD cage. Note the large open areas in the cage that will promote both drive cooling and airflow through the case. The black frame on the back of the HDD cage allows the user to install a couple of 120mm fans (not included) to provide more airflow in this area.
