Summary: Back in 2001, the ATCS series made big waves and Cooler Master was known for uncompromsing quality and innovation with the entire series. Nowadays with the changed economic structure and crowded case market, the ATCS 840 does still hold true to those values. While we no longer see some crazy and "out of this world" innovation in the chassis, Cooler Master has taken all the good, functional and working features and slapped them into the ATCS 840, along with a few smaller...
Pros: Great, competitive price., Excellent construction quality, Three 230 mm & one 120 mm fan included, Plenty of space for big GPUs, Sweet pop up top I/O, Plenty of head room for large CPU coolers, Water cooling ready - includes mounting system, Six individual hard drive trays - easy installation, Removable mainboard tray, Quite a few additional spots for fans, Good accessory package
Cons: Front covers tend to fall into the chassis too easily, Black box in the rear rather useless, Screws to secure expansion cards are placed outside of the chassis, External drive bay locks don't hold as well as traditional screws, Very round and bloated design may not be for everyone
Summary: The Cooler Master ATCS 840 Case is one of the very best full-tower cases on the market. It has all the right ingredients; excellent air circulation provided by three 230mm fans and one 120mm fans (more optional fans can be added), dust filters on all intake fans, plenty of drive bays, looks great, superb design, quality build and so much more. Also, if you're looking for a case to install a large radiator this case does.
Summary: Removing the panel that guards the front intake fan wasn’t the hard part. Putting it back on once we busted the fasteners was. Still, the ATCS 840 is another well-engineered triumph for Cooler Master. If your tastes run more to brushed metal than to blingy windows and lighting, we highly recommend it.

Pros: Motherboard tray cut-out for CPU cooler backplate removal, Constructed with 100% aluminum alloy, Available in elegant black and refined silver finishes, Convenient top-mounted flip-up I/O panel with audio input and eSATA, Low- or high-mount PSU location thermal isolation, Anti-vibration silicon-rubber pads for all drives, Full tower design offers six 5.25" and six 3.5" bays, Excellent cooling fan placement for optimal airflow channel, Liquid-cooling compatible rear po...
Cons: Heavy-weight product despite all-aluminum construction, Negative inner-case pressure may weaken video card exhausting, No sound dampening material, Very expensive premium product, May be too tall for any location other than floor
Conclusion: Starting with the basics, there is simply no denying that the ATCS 840 is one very good looking case. While some people have had their reservations about the shield-like plate on the front panel it is by no means a deal breaker, and from a personal standpoint I believe it to add character to what could have been an otherwise bland design.
Pros: Classic styling. Sexy yet simple., Quality workmanship., Quiet, yet extremely effective cooling via 230mm fans., Ability to install triple radiator with included brackets., Easy to remove filters on all fans., Removable motherboard tray and largely tool-less installation., Room for up to 3 additional 120mm fans to increase airflow further.
Cons: Nothing to report., The Wishlist, Black interior. Enthusiasts like showing off the inside of their PC's just as much as the outside., Wheels. A case that draws air up from the floor needs more ground clearance., Screws not rivets. Not on every part of the case, but adding modularity to the Hard Disk rack would be a great start., Thicker Aluminium side panels., Less plastic. Replace catches and brackets with something more substantial.
