Need Help with DDR400 RAM

[Nevada]

I'm looking to build a new PC after 3 long years. I've been somewhat out of the loop in terms of memory. The system I'll be putting together will be a Shuttle SFF using an AMD Athlon 64 3200+. What are some of the recommended DDR400 memory sticks people are using? I was looking to do a total of 1GB of RAM. Thanks.
