Otherwise, which files do I need to download for a small or standard installation so that I can create my own iso. I guess all packages don't fit in one cd ;-)

Another thing would be, can I replace the old rpm's with the new updated ones so that I don't have to update it. Easier that way if you only have a modem or something ;-) You don't wan't to end up like with windowsupdate.microsoft.com ;-)
