As I've posted recently I'm looking to pick up a new imac in the next couple of weeks to replace my old mac pro. I have an Apple 23" cinema display which if I don't find a use for will end up going in the loft (which seems a bit sad). So I'm thinking I might try hooking it up as a second monitor. My questions are: 1. Do I need to order any special connectors or cables to do this? 2. Will using a second monior put strain on the computer if used all the time? I don't want to wear out my imac too soon. Thanks for the help.
