I would like some advice. Soon, my family plans on replacing the computer we bought in the fall of 2000 with something new. In this process I will be gaining ownership of our current computer. I plan on doing some major upgrading of it and making a sleeper. I just want to know what I really should replace. My friend told me that with a couple hundred bucks I can have a very respectable PC. It's a HP Pavilion built in late 2000. I already plan on replacing the CD-Rom with something faster (more than 4x burning speed), getting lots more RAM, and replacing Windows ME with either 2000 or XP (whichever I can find cheaper/free-er). I plan on keeping the monitor, keyboard, mouse, and case no matter what. So what needs to be replaced inside and what can I keep? Or should I just empty it all out and start fresh?
