perfect example is whitebox, this is redhat enterprise for FREE.

check it out. as for suse as far as i know you can get the suse 9 for free, but not their suse9 pro or any of the pro veriants for free as novel still keeps a portion of the pro distro for some reason out of the GNU project. i do not know all of the details on suse, but i know you can get the RHE for free.
