    Dear all,

    I'm totally new to Apple's products, but wanting to make a switch from Windows to OSX.

    I can buy a late 2009 series iMac 27" at a very good price from a friend. And ... I need to keep it inexpensive, the full price for new Apple gear is outside my reach (and there are no refurb options where I am).

    So my questions:
    • How noisy do the fans on a late 2009 series iMac with a Core i5 750 tend to get under heavy load? That may seem silly, but I'm highly sensitive to PC noise, and where my friend lives it is hard to tell who quiet/loud the machine is.
    • This generation of iMac can have optical drive replaced with a small SSD. Is it important to get SSDs which OSX recognizes and gives TRIM support nowadays, or will any reliable SSD be okay?
    • In case the built-in thermal sensors don't work after I meddle, and the fans spin up to high RPM ... which software is used nowadays to disable/replace the OSX HDD & Superdrive thermal monitoring? :)

    Thank you very much,
