Thanks, I appreciate your response but I'm kind of blown away at how difficult this is to get an answer to my question..especially from an MSI forum. I thought push/pull was a common configuration. I've tried contacting MSI customer service and I can't get through. I tried the chat room with no help and even sent them emails. I've also contacted NewEgg without any help. I also went to my local ACE Hardware store and they didn't have the right screws. I've also checked eBay.
