I've finally gotten sick of all the crappy search functions at places like Yahoo and google groups, so I decided to start my own metalworking forum. It's kinda geared toward the Do It Yourselfer and the weekend warriors, so hopefully it'll be a great resource for those who would like to build their own waterblocks. Feel free to check it out. It just started on 2/19/03, so it may not have much info yet.
