I was thinking about buying an eMac that already has 2GB of RAM installed, along with a 1.4Ghz processor. If I do, I think it'd be a fun project to completely replace everything in it and make it an up-to-date, speedy computer. I would probably need the replace the motherboard to do this though, correct? Is that very difficult? I don't mind spending hours doing this if I know it'll work, or will probably work. I plan on having at least a 3Ghz processor, 6GB of RAM, a decent video card (1GB), and a wifi card. Is this possible? I really would appreciate any info or tips I can get. Thanks.
