Opening up the case

Is there a way to open the case up without destroying it. My case is riveted together instead of just being screwed like all other computers.

Gateway dx4320. want to install sata card. have side panel off but the metal tab for the card opening is not screwed in like older computers but seem to still be attached by small connections to the rear...

I found a picture of the rear of the case and it looks as if there's 2 screw that hold the right side of the case on, if you're looking at the back of the case.
I really wish manufacturers would put thumb screws on the cases instead of actual screws.

I need the cover off so i can install a cdrw and i need to change hard drives, there seems to be two screws on the back an the rest are rivets so how do i get the shell off to get to these areas, all the...

The Compaq desktops use the same basic case. Before opening the case, disconnect all of the cables attached to the back or front of the computer. Remove the two screws that hold the side panel, then slide the panel towards the back of the computer to remove it. Press in on the tabs that hold the front panel (they are on the sides of the front panel) and rotate the front panel away from the computer to remove it. Remove the other side panel if needed (most models do not need this).

Then disconnect the power and data cables from the old optical drive if one is present. Remove the screws holding the drive into the case (or rotate or press in the slides for a tool-free case) and slide the drive foward. Then slide your new drive in and secure it with the screws. (Remove the insert if there was no drive in the bay.) Attach the data and power cables. Then close up the computer, connect the cables and power up the machine. If the drive is seen, the drivers need to be loaded (Windows may do this automatically). If it isn't, reopen the case and make sure the cables are fully connected both to the motherboard and the drive. (With IDE drives, it is possible to connect the cable to the drive 180 degrees out of position. Try turning the cable connector over.)

For pictures, see .

I hope this helps.

The side with the thumb screws is your side panel that allows access to the inside of your computer. On some computers only one side comes off. Hope this helps...

Opening the tower of a VGC-RB42B PC desktop Vaio

There's normally some kind of screw or clip on the rear of the case. Every case is different, some have the sides slide off, others have the top slide off and then the sides lifted up, some come off all together. Others have the front pull off (careful not to break it if you try it this way) and then the sides unscrew from behind the front of the case. Good luck
