Hello everyone. I traded my alienware today for a 27 inch iMac. It works great but there is a constant clicking sound that I am hearing. It is not too loud but it is noticeable nevertheless. I'm assuming it's the hard drive so I wanted to know if this is anything to worry about. When I did a search, most of the people that had clicking sounds were already having problems. There is still warranty on it until january so I can always take it in to apple. Thanks to anyone here with advice!
