This site describes itself as the largest source of ancient Roman information on the Web, with over 70MB of information. I don't know if it's really the largest, but it certainly has a lot of good information. This site appears to be no longer actively maintained.
A page of links, sorted by category (politics, art, military, etc.). Some of the links are to pretty old sites, but the are still mostly good sites.
Lacus Curtius- Into the Roman World
A huge resource, containing geographical information, excellent photographs, original sources with translations, links to a number of other websites, and plenty more than I have room to list here. Someone could spend months just exploring this site.
The British Museum Roman Collection
The Ancient History Sourcebook: Rome
A huge collection of original and secondary sources for Roman history, sorted by categories. Unfortunately, many of these links are out of date. Everything from this page that is still available on the web is listed here. I've lost the organization that was originally done, instead listing the resources by author, but I'm still working on the page.
