4  Remove the screw securing the expansion card. See Figure 3-24. 
5  Grasp the expansion card by its edges, and carefully remove it from the 
riser card. See Figure 3-24. 
If you are removing the card permanently, install an expansion-card 
slot cover over the empty expansion slot opening, and close the 
expansion-card latch. See Figure 3-24. 
NOTE: You must install a filler bracket over an empty expansion slot to maintain 
Federal Communications Commission (FCC) certification of the system. The 
brackets also keep dust and dirt out of the system and aid in proper cooling and 
airflow inside the system.
