Cooler Master ATCS 840 is a full-tower case targeted to users that want top-notch all-aluminum case. Here is a summary of what we found about this case.

Strong Points

• Good number of fans.
• Excellent screwless mechanism for holding disk drives.
• Good number of hard disk drive bays (six) and should please even the most demanding user.
• Anti-vibration mechanisms for the hard disk drives.
• USB ports are distant from each other, allowing you to install two “fat” USB devices at the same time.
• Washable dust filters.
• Support for the installation of water cooling radiators with two or three 120 mm fans directly inside the case.
• Support for two power supplies.

Weak Points

• No speed control for the fans.
• Doesn’t come with the power-on adapter to turn on two power supplies at the same time.

As one could expect, this is an expensive product, but since we’ve seen fully loaded all-aluminum cases costing far more than USD 300 ATCS 840 pricing isn’t bad at all for the market segment it is targeted. It can be found, on average, for USD 267, just a little bit above fully loaded steel cases such as Thermaltake Spedo Advantage Package and another aluminum full-tower case from Cooler Master, Cosmos S.

It provides more features and has a better quality than Cosmos S, even though we like the handles available on Cosmos S.

If you are willing to make a USD 270 – USD 280 hole in your wallet, we think Cooler Master ATCS 840 is one of the best options around.

Usually we don’t give awards to cases on this price range because most of them have too many little flaws that are inexcusable if you are willing to pay that much for a case. ATCS 840 is a good exception, being a practically flawless case. You won’t regret buying it.

For the average Joe, however, there are several other full-tower cases on the market that provides a better cost/benefit ratio.
