BundleBits — search for ISO disk images
BundleBits says this about that: “An ISO, a CD/DVD image or a Virtual Machine DomU (Guest) are downloadable files which contain complete, ready to go applications, operating systems and more. You can find practically anything in download form today, documentation, applications, ready to run Internet servers, fully pre-configured operating systems, music, video, graphic workstations, stock materials, you name it.
