Excerpt: Instead of a god of the sea, Gigabyte’s midtower Poseidon 310 chassis is a petite prince. But that’s merely a reflection of this case’s size, not its prowess. It clocks in at 7.75”x17”x20”—small enough to fit into that nook in your desk or the space under your bed. Even given its small size, the Poseidon supports up to five 5.25-inch devices. We’re unsure why this case—or any case, for that matter—still bothers with multiple external 3.5-inch bays.
Pros: Almost completely tool-free; hard-drive-bay cooling; rubberized water-cooling holes.
Cons: Slightly cramped on the inside; no cable management options; few front-panel connections.
