After removing the front cover, which snapps off quite easily ) We can see that that all mesh grills are equipped with a dust filter.
The rear expansions slots are removable. The USB 2.0 and USB3.0 cables can be hooked up directly to the motherboard. No more routing USB3.0 cables to the rear, just attach them to the motherboard connector.
Major cutout for easy CPU cooler installation, plus the other cuouts facilitate cable routing/management. The Power supply is supported by 4 rubber grommets to dampen vibrations.
Like said before the accessory box is complete. But CMs Stormguard is also inside. What it all boils down to is that you can protect your USB external peripherals ( keyboard, mouse, headset ) from being stolen at eg a LAN party. Just route the USB cable through the Storm Guard, then through the opening above or through one of the precut watercooling holes. The Guard bracket avoids that you can pull the cable, plus it will not allow a USB connector to pass through (if routed through the small opening just above).
Ofcourse if you unscrew the bracket ( just with one screw ) then you are again unprotected. A clever idea, but it would have been much more clever if the bracket screw was on the inside for a more solid protection. But quick theft of external devices is seriously reduced with the Storm Guard.
