No need to do this unless a CD/DVD is in the tray.
The Front Cover comes off from inside the case,
leaving the CD/DVDs' and floppy, if equipped, in Place.
To remove CD/DVD From Trays;
Use a Straightened, large diameter, paperclip to open CD/DVD trays. Look for a small, round hole in the CD/DVD face plates. Insert the straightened paper clip in the hole, gently, till it stops, then push gently, till the tray pops open.
The Front Panel has to be removed to remove/replace the CD/DVD/Floppy Drives.
There are 8 to 10 locking lugs that need to be depressed, pushed toward the Center of the case, (yes, almost all at the same time) to realease the Front Panel.
Refer to Users Manual supplied by jam for posible pictorial guide.
There is nothing to learn from someone who already agrees with you.
