At a garage sale, I got an Antec case witha silent 430W PSU. It came with the front USB, Firewire and sound. In addition, I have 1 120mm fan. That's good. MY green case is now empty. I will switch it's 450W to my Athlon 1000+ who needs one badly from a 250W PSU.
I had a lot of troubles with my hard drive as itkept randomly turning it off. I inserted the molex harder and made sure it wasn't to hit the door.
I got this case for $30...and I owe my momthe $30. :S
This is my case: The Antec Sonata
The link IS my case
