T-Break posted a review on the Gigabyte Poseidon Case

Inside the case we have five of 5¼” screw-less bays and two 3½” screw-less bays along with an internal HDD bay at the bottom that can take three more drives. We like the screw-less design from Gigabyte that secures the drives very tightly preventing you from wasting any time with installing/removing the drives using traditional screws.
