Theme Advice/Suggestions

I need to create a portal type site that pulls in different content from about 4 different websites onto the home page.

There will be no Community or anything on this site, Just a site featuring the latest from various sites. This page may have to pull in latest from blogs on an MU Install and latest from Groups, etc.

I am thinking the right theme will go a long way in helping to get this done. Just not sure which one is the best.

Any Advice please?
