I've been looking at the forums and it seems some people upgraded the CPU on 2010 iMacs. I'm going to upgrade the CPU on my PC and wanted to use its current 2700K in the iMac as seen here: http://www.ifixit.com/Guide/Upgrade-iMac-Intel-Core-i3-CPU-to-Core-i7/8670/1#.T-LHZPX4JW2 The question is, can we do this on the current 2011 iMac? Or has something changed? Searching the forums brings up one account of someone saying they did it. But it didn't seem like a reliable post.
