stla,
Hard to answer since there is no model # or description attached (laptop??? desktop???) but here goes.
I am assuming you mean that when the side panel of the desktop is opened while the PC is running (although I don't know why you would need to do this). There is a setting in the BIOS to enable/disable case tampering, usually called Chassis Intrusion or Case Open or something similar.
Some corporate PCs have this feature enabled so even when the PC is off the case cannot be opened without the Admin knowing about it. In this case there is a little switch near the chassis door.
If you get a "Case Open" warning upon boot you will need to clear the CMOS Case Open Log by resetting CMOS (best) or removing the battery for a few minutes. There should still be an option in the BIOS to turn the feature off.

Every one I've seen had a microswitch mounted in the frame connected to the M/B. You can cut the wires for a start and if the message still comes up after you reset it in the CMOS settings you can short the wires together and reset it again.

Wow.
The "Cover was previously opened" warning is because of a switch under the cover.
Even if the cover is opened while the computer is OFF and UNPLUGGED will generate this.
Especially useful in, say, a college, where someone may be stealing RAM or whatever.
To clear the message, go into the BIOS under the CHASSIS INTRUSION bit. It has 3 options... "Enabled", "Disabled", and if the cover was opened, it will say "Detected". Change it from Detected to Enabled (to tell you if the cover is removed again) or Disabled (to ignore future security breaches.)
You don't have to do anything more than that.
Just my 2¢

Think of it like a seatbelt warning light. Also motherboards have a battery to safegaurd the BIOS. Maybe the Switch is wired up to the battery.
Maybe like a seatbelt it can be wired shut.
This is one thing that can be useful in a setting where you share a room. Sometimes these cases also have a way to secure the case with a lock to keep people from opening your case and stealing your components.
If you do not like my post feel free to point out your opinion or my errors.
