I'm thinking to start my own server and have never used any Linux or Unix OS before. I'm looking for the easiest, least code/programming, most buttons-click-customizing server friendly to MySQL, Apache, webmail, pop3, smtp, videostreaming and all that Linux/Unix OS out there. It must be free and easy to download. All suggestions are welcome! Thank you.

Most of today' bigger Linux distributions have Apache, MySQL capabilities and everything else you need to run a server. Maybe XandrOS (formerly Corel Linux) is the right choice, it has an easy installation routine, or Linspire (formerly Lindows) which more or less imitates Windows. Downloading is easy, get an .iso-image and burn the CD, then install. You can find a large selection of distributions with informations about the features and download sources here: http://www.distrowatch.com/

BUT .... if you run your own server, it's important to keep the security patches uptodate. Otherwise you can easily be hacked. It will be hard to configure your server correctly without any Linux experience. That's what everybody says.

Never used *nix before ?
then the first thing you need to do before setting up a server, it to familiarise yourself with a flavour of Unix.

there are many threads here alreayd about choosing your first linux distro.
alternative flavours are the 3 BSD's (netBSD, FreeBSD, and OpenBSD)
and ofcource OpenSolaris.

all are free.
