Can you be any more specific than that? Since all linux distro's run about the same software it's hard to make a recommendation without more details.
That said, if you're going to a control panel I would recommend Redhat 7.3, as that seems to be what most of the panels are designed for.
If you're trying to optimize for speed, you can roll your own distribution with Gentoo Linux, but this is designed with the advanced admin in mind.
Redhat 8.0 is the only distro to my knowledge that comes with Apache 2.0 active by default, if you want to use the latest and greatest.
Additionally, you might want to look into using OpenBSD, which, while not being Linux per se, is a UNIX designed with security and performance in mind, and not so much as an OS for office/productivity work. Their moto says it all: "One remote hole in the default install, in nearly 6 years!"
FreeBSD is another popular BSD distribution, but I'm not as familiar with it. AFAIK, the difference between Free and OpenBSD is how the development proceeds. Both are Free as in beer: they can be downloaded from the internet without charge.
For setting up a personal server on a home machine, you could go with Redhat 8.0, but also might want to check out Mandrake 8.2 through 9.0. Mandrake has a lot of added configuration tools to make setting up httpd easy.
Not such a simple question, was it?
