I recently upgraded from imac11,3 27" i3 (http://www.everymac.com/systems/apple/imac/specs/imac-core-i3-3.2-27-inch-aluminum-mid-2010-specs.html) to I7-870 CPU. The things that I learned: - You must choose exactly the same model of CPU: i7-870 for maximum compatibility - With i3 CPU, max ram / slot = 4 GB. With i7, it can support 8 GB ram /slot. - if you are dismantling the imac the first time, be prepare to spend 2-3 hours. - be careful not to clean the memory slot - there are stories people pushed the memory slot pins and render it not usable. - Unplug the power cord and let it sit for a few minutes for the electricity to discharge from the capacitor before removing the screen. - it is possible to add a 7mm SSD and placed it underneath the DVD rom slot area. You will need a SATA power splitter and a SATA data cable. Good luck!
