My 2 cents:
Most Linux distros these days install a dumbed-down GUI by default. It's like running Windows, but without being able to play all the cool new games, and having to work around things like online banking sites that only work with Internet Explorer, etc. So if you just want to install Linux so you can say you did it, don't waste your time.
If you REALLY want to learn Linux, don't install all the GUI crap until you learn the basics first. Using it as a crutch along with all the various setup wizards, prepackaged programs, etc. will virtually guarantee that you never really learn anything.
Force yourself to learn how to the shell, the vim text editor, command line-based commands, basic bash scripting, edit config files, compile source code (in either SRPM or tarball format), administer users, keep your packages up-to-date, and recompile the kernel. Once you do all that, then you've earned the right to get lazy and start using X-Windows. But if you've stuck through all that, you probably won't want to by then.
