Theoretically, the rotation of the motherboard tray makes for easier cable management. By flipping the board 90 degrees, the power connectors are next to the bottom-mounted power supply, eliminating the need for extension cables.

3.5" drives install on their sides via plastic drive sleds. The 5.25" bays have a simple one-touch locking mechanism on the left side which is secure enough to hold an optical drive in place. Holes for screws are provided on the other side in case they're needed. A cross beam runs across the center of the case with plastic tabs designed to help secure expansion cards.

The myriad of mounting holes on the motherboard tray are more visible from the back. Mysteriously, there appears to be far more holes than necessary for ATX or even EATX boards.

Cable management may be a bit tricky as the tray only has two large holes on the side and a few small ones at the bottom. Molex connectors won't fit through the smaller holes, nor will more than one USB/FireWire/Audio header cable due to the rear fan holder which clips into the same holes.

The two 180mm fans blow upward and are housed in plastic mounts that screw into both sides of the case. The one pictured left sits just above the power supply and blows toward the expansion cards. The one pictured right provides airflow for the hard drive area.

The fans, though massive, are low speed models drawing only 0.20 amperes so they can be plugged directly into motherboard fan headers. They exhibit good geometry, with trailing edges nearly perpendicular to the struts. The edges of the blades are the sharpest we've ever seen, perhaps to minimize air resistance, but sharp enough to dice vegetables or fingers. They also have sharp notches near the hub, so caution should be used when handling them.

Airflow Note: Much of the direct airflow in the motherboard area comes from the rear 180mm fan, and there is only one 120mm exhaust fan, which is quite an imbalance compared to the two 180mm intake fans
. Even though the top panel is quite open, in total area, it's less than the area of the intake, perhaps even less than the area of the two 180mm fans. If there is any airflow bottleneck in this case it's most likely to be at the top, the exhaust point. This is the only way hot air can exit.
