Building on the legacy of its TriStellar series cases, DeepCool unveiled the bigger, four-lobed QuadStellar chassis. Unlike the TriStellar, which housed mini-ITX motherboards, the QuadStellar is much larger, and designed for full-fledged ATX motherboards. The central axis to the four lobes is more functional than it is on the TriStellar, as two opposing lobes can now meet in the middle to make up a large continuous chamber to house the ATX motherboard, and its 8 expansion slots. One of the other two lobes houses the PSU bay with a few drive bays; while the other lobe has three additional PCI-Express x16 slot risers, and a few more drive bays. The case measures 523 mm x 485 mm x 485 mm. It features nine 3.5-inch and twelve 2.5-inch drive bays. DeepCool plans to launch this case by May 2017.
