You could try your local mirror ;-)

I did find that later.
For some reason it is not given (no site in Ireland is given) in the list of local mirrors which I get if I follow the links in the title bar from http://www.centos.org Downloads=>Mirrors=>CentOS-5 ISOs=>x86_64
But not to worry - I have the DVD ISO now.
