You can expect it in retail stores by the end of September.
The CM Storm Scout II will be an ATX mid-tower case, supporting extra-long graphics cards, including NVIDIA GeForce GTX 690 and AMD Radeon HD 7990 (if it ever comes to be). Much like the original, it will feature windowed side-panels to let your show off your gear. The teaser pictures reveal the case to be heavily ventilated, with large cutouts for water-cooling plumbing.
