The FSP CMT520 should not be mistaken for an evolutionary step up from the CMT510. It does not only come with a completely different internal feel, but also a different external look. The changes result in great dual radiator support, better RGB fan compatibility with motherboards, and better storage capabilities.

he FSP CMT520 may carry a similar model number as the CMT510, but is not simply a small evolution of that chassis. Instead, it is a completely different beast offering a totally different design both externally and internally. It combines steel, glass, and plastic to create a more elaborate look and offers much greater dual-radiator support and an upgraded RGB controller for the four included fans.
