Cooler Master is a very reliable source of computer products, and
the 690 case is no different. With minimalistic black styling, a mesh
shell, and chrome outlines, the 690 is one of the most visually
appealing cases I have ever seen. Combined with an arsenal of tool-less
features, the 690 case is a top-notch case. However, due to a lower
level cooling performance, the 690 does not shine as bright as the more
efficiently cooled cases.
