Thermaltake's new mATX case is stackable, rotatable
 

Another case has joined Thermaltake's microATX roster. While it looks pretty plain from the outside, the Core V21 has two unusual features: it can rotate to allow for either horizontal or vertical motherboard placement, and the chassis itself is designed to be stackable. In a stacked arrangement, Thermaltake says users can put vital components in one case and liquid-cooling devices in the other.
