Introduction
Upgrade mid 2010 27 inch Apple iMac from a '''Core i3''' 3.2GHz (Dual core) to '''Core i7 '''2.93GHz (Quad core) processor.
I used this guide for disassembly and reassembly.

Also added a 3TB SATA drive and 32Gb of RAM to max out this system under Lion 10.7
* Update : Removed the 3Tb SATA drive and replaced with 512Gb SSD and upgraded to Mountain Lion 10.8
* If you upgrade or change the HD, you will need to buy HDDFanControl software to control the HDD fan which will run at full speed otherwise.
* April 2013 - 1 year later : This system has been absolutely ROCK SOLID with no crashes, no kernel panics and no freezes!
* April 2014 - 2 years later : now running OS X 10.9 Mavericks successfully with zero issues. System continues to be fast - but is starting to show its age compared to Sandy Bridge, Ivy Bridge and Haswell architectures! Newer apps are starting to creak at the seams & the beachball is now a fixture.
* October 2014 - 2.5 years later. Now running Yosemite 10.10. Still fast (for its generation) and very stable. No problems to report. Lack of built-in Bluetooth LE (v4.0) means Handoff does not work. Will try a BLE dongle as a possible workaround.
* April 2015 - 3 years later. Yosemite 10.10.3. Continuity works but Handoff does not (lacks built-in Bluetooth LE v4.0). Not as fast as my Haswell Macbook Pro or 2010 Xeon 12 proc Mac Pro, but still rock solid. With these simple mods, I have gained years of additional service out of this "obsolete" machine!
