2.5.2 Installing a 5.25 device
Make sure to unplug the AC power supply before adding or removing
any 5.25 fixed device or other system components. Failure to do so
may cause severe damage to both the motherboard and the system
components.
1. Use thumbs or a flat-head
screw driver to detach the
hooked tabs from the left
side of the front panel.
Take caution in removing the front panel cover. Do not use too much
force when installing or removing items.
