Just try selecting any recent model Dell server from the support page, eg PowerEdge 2950, goto downloads and look inside the system management section.
We are trying to install Server 2003 R2 and are having problems which can apparently be solved by using Dell OpenManage 8.7 (rather than 8.4 which we are using) but I cant for the life of me find anywhere to download this new version on the Dell website.

I suggest getting the 'Dell DVD ISO - Dell Systems Management Tools and Documentation', try http://support.euro.dell.com/support/downloads/format.aspx?c=uk&cs=RC1050265&l=en&s=pad&deviceid=17861&libid=36&releaseid=R250023&vercnt=4&formatcnt=0&SystemID=PWE_2950&servicetag=&os=WNET&osl=en&catid=-1&dateid=-1&typeid=-1&formatid=-1&impid=-1
Dell's latest server management tool is 'Dell Management Console'. You can get this by following through from this link http://www.dell.com/content/topics/global.aspx/sitelets/solutions/management/server_monitor?c=us&l=en&cs=555
