If you use individual content centers you will have issues when another computer opens the file and can not resolve the links to the content center that was used to create the parts.

If the network issue can not be resolved in a timely manner, I would suggest saving the content center parts local to the project by opening them and doing a "Save As" copy to the working directory and then use the "Save As" parts in your assembly. There may be lots of duplication in parts, but it is really aweful to have to resolve tons of links everytime you open a model.

Good Luck
