Above you see the bottom of the case. Notice the leg supports. They do extend out to provide stability for this heavy case. This combined with the weight makes it about impervious to even a tornado going through your house. Also notice the slot at the far right on the front bezel. The included washable filter fits right in there. And combined with that slot the front bezel has larger open grills to allow for very good intake airflow.

Behind that front grill is the included removable air filter. Awesome idea that EVERY case should have! A vacume works well for removing the dust. On the right you see the removable drive cages. In the lower one where your hard drives will go there is a place for an 80mm fan. The cages simply slide in, then lock into place with the lever. Below is a more full view of the front that also shows where a second 80mm fan can go. There are places for as many as five fans. All fans simply snap into place, no screws required.

The above picture shows the rear view. Those 2 80mm fans are included and as you can see, the rear fan grills extend out slightly and have large vents so not to restrict air flow. Having two rear exhaust fans is a plus to help remove hot air from the case and especially from the cpu, which will usually be closeby depending on your motherboard.

On the front and just below the door there is a small compartment that when you flip up the small door you'll find two usb ports and one firewire port. All necessary cables are included to connect to the motherboard. Convience, we like.
