Shaunkad,
It is typical for all COOP managers to offer 'parts only' options for the above stated reasons. This is a convention we typically use when offering any type of COOP with few exceptions. Just make sure to order the correct kit so that you get a PCB and parts, if that is what you require. The 'parts only' option is really to help you guys out (for those not requiring the PCB) and it does not really create much work difference for the COOP manager.
