Do i need to screw in the HDD with the Fractal Design Focus G Case?

[chaselgator]

I went to go screw in my hard-drive but realized that none of the screws the case came with are long enough to screw in the hard drive. There are prongs that stop it from falling out though, so I don't think im supposed to screw it in. Am i?

Should not be the case, their drive bay are supposed to be screw less.
