I would like to be able to replace a cooling fan that is ratteling. Just like a computer, what do I need to know about just removing the rear panal and what fan do I need. I can probably go ahead and work the panal off and grab the noisy part off then go into the local electronics store, I just thought I would give the guru's a shot before I travel into the nearest metropolitan city (Edmonton AB) which is 100 kilometers away. So if you can ease the pain, it would be much appreciated. By the way I am fom Calgary Alberta. GO-FLAMES-GO. LOL Dean Bellefountaine
