It might be possible, though my soldering skills are terrible and I don't want to kill this computer. My friend has another and he says it should be faster and I could keep the hard drive this time. I bet it might have an AGP slot. I don't know when he will have time to bring it over though as I had to wait a few weeks for him to get this one to me. I have about $100 to spend on parts to get this machine to play Counter Strike: Source, I know a person who has many computers and parts so I bet I can spend a pretty small amount to get what I need.
