I just have an old PC I'm giving to my sister. It's a Dell Optiplex GX150 with Windows 2000 installed. Other Specs include: Intel Pentium III 900MHz 128 MB of RAM Installed Two (2) DIMM slots 10GB IDE Hard Drive I want to upgrade it as it is obviously outdated and slow. I plan to upgrade the RAM memory by installing a 256 MB memory module in it and installing XP as well. These thing I know how to do. My question is the hard drive : How do I upgrade the 10gb hard drive?
