Yahoo SiteBuilder Compatibility with Mac

I plan to purchase a new Mac desktop. I have a website, www.colorantshistory.org, that was built with Yahoo SiteBuilder software, and that runs on my Dell PC (Windows XP). Is it possible to transfer this website to the new Mac, say by importing it? It's a very large website, with over 100 pages and 1,000 photos, so rebuilding it page by page on the Mac would be tedious. I know I could always run Windows on the Mac with BootCamp, but I have an aversion to putting Windows on a new Mac because of the constant maintenance and security updates required. Any advice would be very appreciated.
