We'll be taking a closer look at the Coolermaster ATCS 840 Aluminum chassis. From my first impressions, the chassis does look good ... better looking than the HAF-932 I guess. But what particularly appeals to me is the all-aluminum construction, the build quality and the cooling performance.

"The smooth and clean lines of the Coolermaster ATCS 840 is what makes this chassis so appealing. Constructed of high quality brushed Aluminum ... it offers excellent build quality, it's light-weight, strong and looks great. What's more, the cooling performance is just as impressive. "
