Coolermaster HAF-X help

I need help trying to pop the lid on my coolermaster haf-x to replace the 230mm fan( I may not even have to...). i have not messed with any of the fans as of yet. but i want to start on the 230mm so i do not haf(:P) to worry about it later. :D

And you need help in what exactly? It's just a couple of case screws and top panel clips...
