Installing Optical and Floppy Disk Drives
To install optical or floppy disk drives you will need first to remove the meshed cover that is in front of the bay that you want to use. As we already explained, to remove these covers you need to first open the two long side latches present on the front panel.
If you are installing a floppy disk drive, you will need to first install the two metallic adapters that come with the case on the drive.
The screwless mechanisms for installing 5.25” devices are really easy to use. They have a button that pressed once locks the drive into place. To release the drive, just press the button one more time.
