If you consider Mandriva a desktop distribution, then you should consider Fedora, Ubuntu, SuSE and all alike too. They're aimed at desktop use. Any one of them can
however be turned into a webserver, but that means (if you ask me) removing a lot of stuff and configuring default settings towards a webserver. I wouldn't choose SuSE nor Fedora right out of the box for a webserver, it's so much work to get those big distributions stripped off the unneeded software and made efficient for server use. But then again, if it's your personal server, you think you can manage it and are not worried about security and efficiency issues (you should be), go ahead; I think it's good to learn to do the job with an enough-easy-to-use distribution of Linux than spending countelss hours hardening some really rude distribution and once it's ready, notice that you're actually not able to do all the stuff you wanted because it seems so difficult. Better start off with easier methods because they're available
anyway SuSE wouldn't be my pick. Maybe Ubuntu's 6.06 LTS Server 'edition' was a good start; it offers LAMP if you want, and a support longer than Fedora's or SuSE's for exmaple (if I'm not mistaken). And if you, after some time, feel it's not your thing, you can always switch over.
