Check this link out-->http://www.linuxlinks.com/Distributions/
Youll find brief informative descriptions on most popular linux distros. (I personally found this site the easiest to use):)
Once you find a distro you think you want, you can click on the distros name to connect to a site with more descriptive info and info for obtaining that distro.
Still don't have enough info??
Can't Find a Linux thats right for you??
