Turns out the RAM that was chilling in that Viper that I picked up for $100 is DDR2, so I dropped it in my build and I now have 2GB dual-channel memory rolling until I get a chance to pick up some 2x2GB RAM sets. Should be upgrading to 5GB in April if I have anything left after Sakuracon, then getting a GeForce 9800 in May in preparation for SCII, and finishing it off by upgrading to 8GB in June, at which point I will no longer consider this computer a work in progress.
