Hi, Yesterday i ordered myself a new imac with vesa. I already ordered one last december but it got canceled (to long story). Now i ordered one with 3-5 delivery Time and it will be here on 9.April ? Maby cause of easter... Mainquestion: What should i check after unpacking the imac? I read about: damage to the aluminium high pitched noise dead pixels in screen Yellow tint screen Bubbles or Dirt under the screen ratting noise out of fan area ghosting of the screen weird clicking/popping noise in a random fashion that appeared to come from the bottom part of the screen and which seemed to move from left to right Anything else i should check?
