I know it's a little offtopic, but may I ask you why you choose RedHat as distro?
Why I ask this? Often, people that have limited (or even no) knowledge of Linux say they want RedHat. Why? Because it's Redhat! Why? Euh... Indeed, they don't know why; RedHat is wellknown, so a choice is born.
Although this is a kind of personal matter, I wouldn't want to advice RedHat for what most people want to use it for: common desktop applications. RedHat is fine for serious workstations, but somewhat spartan for standard desktops.
If my post surprises you a little... well just let us know, so we can help you choose the best distro just for you
