Nzxt Guardian case
 

On the bottom of the case two small lids can open and they cover the two extra USB ports in the front and the sound ports that will make your computer usage easier. Remember to plug the cables in right though so double check your manual on how to do this. The front also has a door that covers the drive bays. The door clips on pretty hard so don't worry about it opening when you don't want it to. Five 5.25 drive bays and two floppy bays are available on this case.
