I am eagerly anticipating delivery of an 27" iMac and I need to raise the shelf above my desk so it will fit.


I know the height of the iMac but I was wondering if there were any minimum clearence figures anywhere, I haven't been able to find any.


Also, a question for those with a late 20012 27" iMac, does it get hot at the top, is there any reason I need a large gap above my iMac below the shelf.


Thank you for your help

I have a 24 inch at home, a 2011 27 inch at work, and a new 27 inch now with me at home. I am astonished at how cool this thing is. My work i7 27 inch gets VERY HOT on the left upper corner... freakes me out. This thing is just barely warm in spots.


And yes... the Nest is also cool I dont regret dropping the $$ on it one bit (had to throw that in).

I have a new iMac 27" and the air inlets are at the bottom and the outlet is in the middle of the back of the case, hidden behind the support arm.  If you search for pics of the inside of a new iMac you can see that they did some awesome air flow design inside to pump the heat out without it sifting up through all of the non-heat generating components which could shorten their life.


You can see the outlet vent in the picture already posted.

I'm relatively new to the Mac platform having owned only a 2009 24" and 2010 27" prior to my current late-2012 27" both of which vented out the top which became very warm in normal everyday use. 


This 2012, the "iMac13,2", is the coolest I have ever been around.  The top of the computer, after having been on for weeks, is still at room temperature.  Touching various areas around the back doesn't reveal any area that is more than very (very) slightly warm. I don't see how any space with any venting at all could be inadequate.
