Riotoro CR1080 case is a more compact ATX enclosure
 

New kids on the block Riotoro have announced a compact ATX enclosure called the CR1080. This case uses a dual-chamber, inverted-motherboard design to fit full-sized ATX motherboards, power supplies, and full-length graphics cards in a space that measures just 9.6" x 14.1" x 15.5" (WHD). Thanks to its compact dimensions, the CR1080 has limited space for storage. Two combo mounts for 3.5" or 2.5" devices, a single 5.25" drive bay, and a dedicated 2.5" drive mount should serve the needs of most users these days, though.
