A standoff is a threaded separator of defined length used to raise one assembly above another. They are usually round or hex (for wrench tightening), often made of aluminum, brass, or nylon, and come in male-female or female-female forms. In electronics they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing an electrical short.

Standoffs, Also called spacers, are round plastic or metal pegs that separate the motherboard from the case, so that components on the back of the motherboard do not touch the case.
Two packages are housed in carrying case assembly and two are housed in the carrying harness; each package contains six standoffs

Usually, when you buy a computer case it comes with standoffs which get screwed on to the case (there's usually at least 6 and as many as 10) and then the motherboard sits on those standoffs instead of on to the case itself. The motherboard standoffs serve the purpose of avoiding direct contact between the motherboard and the case itself so as to avoid a possible electrical discharge which would in turn damage the motherboard. There are holes on the case where the standoffs should be placed.
To attach a PCB to a case, you can use standoffs, screws, or clips designed for securing PCBs. First, align the PCB with the mounting holes in the case, then insert standoffs into the case holes if required. Secure the PCB using screws that fit into the standoffs or utilize clips that hold the PCB in place. Ensure that the connections and components are not obstructed and that the PCB is properly grounded if necessary.
