On http://www.linuxiso.org/ you might look at the SME server. I have three servers, 1 RedHat 9.0 (testing on a laptop), 2 RedHat 7.3, and one SME 5.5 (Counter Strike Server). I have found the Redhat 7.3 are the easiest, but don't support WiFi PCMCIA cards, which is why I have the RedHat 9.0 on the laptop. I used to have have 3 Windows 2000 Servers, one running coldfusion/IIS and the other two running Apache/PHP/Perl. I will never go back to windows personnally, but I will have to keep up2date on it for work. It took me three weeks to convert all the boxes and get familiar with compiling, apache, bind, and php the way I wanted it, and the servers working correctly. You just have to dive in. And before you dive in, find out if you have a LUG (linux users group in your area) and get on their mailing list.
