Actually, this can be done in almost any modern CMS. Looks like several RSS streams held together by a framework. What CMS is best to use will ultimately depend upon what exactly you're trying to do. Drupal is a heavyweight CMS, and I wouldn't use it to just put up RSS feeds. However, if you're trying to do a much more complex site (with forums, blogs, etc.), then yeah, you'll want to go with a powerful system. Just be prepared for a learning curve (which every CMS has).
