http://www.novell.com/products/desktop/ then click the link marked
Download Eval and make sure you follow the instructions. This is only for the desktop client, if you want the server you will need to go back to the Products page and select the Enterprise Server link, click the download link again and follow those instructions. You did read the website didn't you?
Of course, you could just go down the
www.opensuse.org route. Unless you need it for a corporate in which case the main Suse is the way to go.
