Hi everyone. I'm new to the Mac world, so I'll keep it brief. Save a brief stint on an iBook, I've never owned a Mac. I had to learn them to use FCP for a class at school, and I fell in love with the OS. I currently have a P4 1.2 box that runs Windows XP. Actually, to say that it runs would be a misnomer, but I digress. Anyway, I am looking to get a secondhand Mac to run OS X. I don't do much with my machine. I maintain a webpage for my fraternity, surf, word process, and e-mail. I've found a 450mhz Cube with i.5 gb ram and a Radeon for $800 in perfect condition. Is this a good buy, and will it be sufficient for what I need? I have heard about OS X and its ability to tax a system. Will this machine be too anemic? Thanks for your input!
