Hello, 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? Crucial.com 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: http://www.xlr8yourmac.com/systems/iMac_g4/imacg4_takeapart.html) 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.
