Rails For 5.25" Drives
DVD or CD drives are not attached to the case with screws; instead, the 5.25" drives are inserted in place on two guide rails each. The drives engage with a solid, audible click. But watch out during installation, because the edges in the Revoltec case still sport some burrs.
5.25" drives need special rails for installation.
The mounting rails can be used for all drives and fan-speed controllers
It takes only two fingers to remove the engaged drive.
