Hiya, I've had my order In the queue for a while and excitingly the build date is approaching slowly but shortly. Thinking of making a few small changes to my spec (nothing major at all - just adding an internal disc/blu ray drive) and wondered if anyone knew if this would push the build date back at all? Assuming the parts are in stock I don't see why it would - but just wondered if anyone had any experience with it? Thanks!
