Hardware questions

[Josh Stephenson]

Hi everyone,

I hope this is the right place to send this question.

I need to build a web environment for a high traffic content-driven 
website.  My server experience has been somewhat limited to the software 
and I'm not sure exactly what would be the best hardware configuration 
for a site like this.

I'm thinking I need to have three machines.  One web server that sits in 
the front, one database server and one media (video and image) server. 

I am asking for suggestions on processing power, hard drive space, raid 
configurations from anyone who has done this type of thing before.

Thanks a bunch,
Josh
