iFixit, who is a proponent of replacing everything in your system, does not provide a guide to replace the RAM (only the entire logic board, on which the RAM is soldered). This alone should tell you that it is something that should not be attempted by users who are not professionals. One user did ask in their forums if it was possible. Here's one response: ...

A friend of mine recently upgraded his MacBook5,1 (2009 core 2 duo) with 2GB to Mavericks. It wasn't the most pleasant thing, but it actually didn't work out too bad for him and he even thinks there was a slight performance increase (I'm assuming due to the memory compression stuff being a touch faster than swap).

A 2009 machine is certainly able to run the latest software - it looks like yours is an iMac9,1 : http://www.everymac.com/systems/apple/imac/specs/imac-core-2-duo-2.66-20-inch-aluminum-early-2009-specs.html Memory for that machine maxes out at 8GB, which runs about $100. Everything would be better with more memory. ...
