Motherboards

Chapter 2 covered motherboard replacement extensively, and here we discuss issues related

to building a computer from scratch or disassembling a computer: I/O shield, standoffs, and

retaining clips. Some cases include a standard I/O panel shield that may need to be removed to

install the I/O shield that comes with some motherboards. The I/O shield is a part what allows

for optimum air flow and grounding for the motherboard ports. The I/O shield helps ensure

the motherboard is installed correctly and properly aligned with the case. Figure 4.11 shows a

motherboard I/O shield.

Some computer cases have plastic or metal (commonly brass) standoffs that allow the

motherboard to be screwed into the case without the motherboard solder joints touching and

grounding to the computer case, causing the motherboard not to work. Some standoffs are

plastic, and they slide into slots on the computer case. Do not remove these types of standoffs

but just leave them attached and slide the motherboard out of the slots. The most common

type of standoff is a metal standoff that screws into the case; this standoff has a threaded side

that the motherboard sits on and a screw that attaches the motherboard to the standoff, as

shown in Figure 4.12.
