If you intend taking the panel off to have a look the first thing you should do is Switch off at the Wall Socket.
Once you have the panel off you should be able to identify some of the main components.
The Mother Board is the big (green in the photograph) circuit board that everything seems to be attached to in one way or another.
You should notice 2 large fans.
Some of your hardware gets very hot. If it gets too hot your system can be damaged. These fans are used to help to keep the inside of the case at a reasonable temperature so that the components can operate normally.
These fans are dusty. If yours are similar it is a good idea to keep them dust free. They are more efficient this way.
Also make sure that the case vents are clear from dust too.
It is worth pointing out that your system may not have SATA cables if it is an older computer.
If it doesn’t then it will have IDE Cables ( or a combination as this one has ). IDE cables are broad grey cables that are used to transmit data.
This photo shows the connections in a little more detail.
