Antec Sonata. It's a tad more than 100, but it uses 120 mm fans so it's very quiet and comes with a silentpower antec 380w. It also uses rubber grommets for hard drives so it's really quiet. It's also a nice black and is small and light. I can't say enough good things about it. The only bad thing I have to say it its cooling ability is kind of poor without a real intake fan, but it's still good.
