    I just bought a 20" flatscreen iMac from ebay (the sunflower). It comes with 256 megs of RAM, in one factory-installed slot (DIMM), and another empty user-accessible slot (SO-DIMM).

    The Apple support site says it comes with:
    "256MB of PC2700 (333MHz) DDR SDRAM expandable to 1GB; one 184-pin DIMM and one open user-accessible SO-DIMM slot"

    I want to upgrade the RAM as much as possible. Searching online, it looks like I can "unofficially" upgrade it to 2gb with no problems. But how can I do that? only sells 256 meg and 512 meg chips, making it impossible to even hit the 1 gig mark if the factory-installed slot isn't easily accessible (and it doesn't look like it is:

    Can I get it to 2 gigs? Or even 1 gig, 256 megs?
    How much can I put in, and what do I have to buy? Thanks so much for the help.

    Yes it can take 2 gig, some info is in this thread

    I have a 17" 1Ghz G4 iMac which is in for upgrades at the moment, including 2 gig of RAM. I was not confident in installing the non-user accessible RAM myself. Whilst I'm at it I am getting a new Superdrive, a 500 Gb hard drive and a fresh PRAM battery put in. I plan to use it as a music server and web browser.
