Hello, all.
Yes as stated below: the spacers are also functioning as insulators. 
There are many potential points of contact between  various motherboard 
components and the case  "pan" , which is a reason to use 'stand-off' 
spacers that are  of low conductivity materials. There used to very 
great concern about localized magnetic field generation inside comp. 
cases, as well as the generation of electrostatic fields emanating from 
fan airflow. Over the years with higher buss  frequencies, etc.. there 
is less concern. However the standoff insulators do need to be in 
place......... they also provide for cooling airflow.
