WOW! Thanks everyone for all your help, and fast replys!
Well then, i hope i have the correct kickversion

But i have actually ordered 3.1 roms for both the 600 and the 500

Have to sit tight until they arrive, if there is the wrong ones in there.
Could someone maybe post a image on the bay for the 2.5" harddrive in the 600? Im a bit affraid that my adapter have the connector angled wrong, and there will not be enough space for the IDE cable! But i hope that wont be a problem
