The new Elite 431 builds upon Cooler Master expertise & delivers high-end features in the affordable market space. Cooler Master believes that just because something is affordable, it doesn't have to lack features or be a "budget" product. The Elite 431 features a classic black Cooler Master design with clean, yet attractive lines. It has been built to last & uses high quality materials, unlike many "budget" products that tend to use cheaper materials that don't last. It's also been designed to keep the components inside the case cool & not only does it have space for plenty of additional cooling fans, but it can also be fitted with large CPU coolers, such as the Cooler Master Hyper 212 Plus.
