Isn't that covered in the manual? I know drive installation has been in every Antec manual I've looked at. Not that I'm trying to discourage you from asking for help, but you don't need a new thread for each piece of hardware that you're having trouble fitting. Read your manuals first, and if you don't find the answer, then come ask, and keep all of your questions together in one thread to make it easier for people to help you.
