The Case...

The first step to assembling a PC should begin with the removal of the case cover. The easiest way to identify which screws to take out is by which screw heads are completely surrounded by the painted edge of the cover.

Computer cases look pretty similar to each other. At the right is a pretty standard example of what you're working with.

Notice the empty space labelled 'Power Supply Port' for future reference. I will refer to this in a bit.

After accomplishing this, it's time to prepare the case to put in the motherboard!

The picture shown above displays how to take out the motherboard pan, which will make mounting the board and connecting the cables much easier. However, some cases won't have this option, so assembly may occur fully within the case.

I typically save myself the hassle of taking things apart and reassembling them by putting together everything within the case; it really just depends on how nimble you are with your fingers.

The Power Supply...

You may have to install the power supply yourself. If so, insert the power supply so that the power connectors are facing outwards (as shown). The four circled screws are the important ones you need to screw in yourself.

Make sure that the power supply you are using is at least 350 Watts. Anything below this will prove inadequate to fully power your PC.

After taking out the motherboard pan and installing the power supply, you are ready to start mounting items on the motherboard!

Tip: By just spending $10 or $20 more on your case, you can significantly improve your computer's overall 'looks'. While this definitely doesn't make it run any faster or work better, it could potentially (if you purchase one of my recommened cases) reduce the sound coming from your machine, improve airflow... and also make it look more distinctive (and something to brag about!).
