DNS - BIND ETC

I've just picked up a new domain, and want to play host to it.

Before I proceed, a coiuple big picture questions.

I would rather not have one machine be all the components of my

hosting. I want to break up the host service over a few machines.

I'm thinking one machine as the name server, one machine for the web/http,

and one machine for mail etc. Is this typical for growth?

I'm reading all the "How To's", but respect the groups ideas, and

i'm not in a hurry.

Thanks
