Element Case has secretly announced its latest addition to its iPhone metal case lineup called the Sector 5. This is Element Case's most extreme and over-engineered machined aluminum bumper case yet that features a radical new design. The Sector 5's CNC trussed design is extremely rigid yet lightweight. For the first time, the Sector 5 utilizes a unique multi-link fastening and modular system that claims to enable users to quickly install and remove the case off of their phone using just one screw, while the interesting modular construction will allow for future add-ons and upgrade accessories.

The Sector's anodized aluminum is finished off using Element Case's brilliant matte Flux coating in a gun metal grey color. The Sector case will not interfere with the iPhone's reception thanks to its plastic RF bridge insert. It'll include two black and grey Ultrasuede back plate skins and a transit kit. Element Case's new Sector 5 case is available for $140.
