I just bought this imac 350 yeterday, I;m new to mac and willing to learn as muchs as i can about them and to start with, I'd like to install OS X on it. I put a total of 512MB f RAM into it but it still has the 7GB HD, and i want put in a 120GB one. So is anyone willing to help me with this stuff? Any tips for a Mac noob are also welcome, and once i'm done with this, i would also like to hook up this mac to my windows network. Replies ASAP PLEASE~ I'm dying to have this baby running like new (btw i know 350mhz is not that much but it is a beginning ^^u)
