I agree that Antec is good case for this. I have a Sonata with four HDD and two CD/DVD drives and there is still room for a couple more drives. Some have said that cooling has been an issue with this case, but I haven't experienced it. I have XP 3000+ Barton with 1GB PC3200 and the system runs around 23-25 degrees C with the CPU running at 51-53 degrees C.
