We also have one of these. It was my main machine for almost four years. It now interfaces with my wife's embroidery machine and works quite well. I have put an SSD in it and also maxed out RAM. She uses an older version of Fox on it and, of course, it is not very secure, but internet use is very minimal. Plastic top case is chipped on the edges, but for a 13-year-old machine, it still work quite well.Well, if we're writing about old systems...One of my clients gave me an old white MacBook (4,1), whose 80GB hard drive I wiped and reinstalled Snow Leopard on. Amazing how well it runs with only 2 GB of RAM (and I have a couple of 2GB modules on the shelf looking for a home). I imagine there are thousands of these still working (though the plastic is cracked and stained). Now, I know best security practices would strongly suggest this machine be kept off the Internet, but I wonder what would keep it safe (other than wiping it and running Linux)? Probably any Internet apps that could run on it wouldn't even be allowed to connect to most servers.
