Hello friends,
I order a new 1U server (X3430, 4GB RAM, 2 x 500 SATA HD).
This server will host my projects (about 10) and more projects (about 100).
I'm working with almost all major Linux distros (RHEL, CentOS, Fedora, OpenSuSE, Ubuntu, gentoo, Mint, Debian, zLinux and more....) but it's always my customers servers not mine.

So, I'm wandering which Linux distro will be the best for running as an Apache Web Server, PHP, MySQL? gentoo, debian or the simple CentOS?
I need a reliable system, good speed and performance and security.

Please advise, which Linux distro is the one for a Web servers?

Thanks.
Miki
