Take two pieces of the Tension Clips and mount them onto the sides of 
the 5.25" device.  Make sure the metal portion is angled on the outside 
and facing forward.

Slide the device into the drive bay until you hear a clip.

5. 

Mount the other devices accordingly.

Connect a large 4-pin white connector from the power supply to the 
male 4-pin connector on each of the devices. After you have finished the 
installation, carefully use your thumbs to push the plastic drive bay covers
off the bezel and attach the bezel back into the case.  Like the metal 
plates, take off the covers that covering the drive bays you are using now.

IDE Cable Connection

This is for IDE devices only.  
1.

After you have connected the devices to the power supply, you 
need to connect the IDE cables between the devices and the 
motherboard.

2.

For hard drives and CD-ROM’s, use the 40-pin IDE ribbon cables.
For floppy drives,  use the 34-pin ribbon cables.  When you connect a ribbon 
cable to a device, make sure that the red strip is toward the power connector.

The side that attaches to devices should be the side that has 2
connectors. This will enable you to connect another device if you wish.  

4. 

Connect the far end of the cable to your motherboard on the IDE port.
