So from one of my friends I'm getting an iMac G3. I am wondering how much of it I can upgrade and some of the uses I can give it. Here are the specs: - Mac OS 10.3 - Something like 198MB ram (think that's off but I don't remember the exact number) - 133MHz PowerPC processor - 6GB HDD. Can I upgrade the ram and/or hard drive? Would it be able to run OS 10.4 smoothly if I am able to upgrade the ram? If it could run 10.4, where might I be able to find a copy? Thanks in advance! EDIT: Turns out it's a 333MHz processor due to the fact that it's from the "fruit colors" line.
