Product Description

From the Manufacturer

Re-Introducing an old friend:
ATCS 840 constitutes a classic all-aluminum design that builds on the legacy of the original ATCS design. The aluminum construction not only allows for a lighter weight but complements the thermal design seamlessly with three 230mm fans, dedicated air duct for graphics card cooling and HDD cooling module for superb cooling.

What's New:
Extra attention was paid to make sure this elegantly designed chassis is not only easy to install but easy to maintain. This includes: slide-out motherboard tray along with cut out CPU access for easy removal, tool-free HDD casing, and patented finger pressing 5.25" drive.

Simplicity:
Lastly, it gives users the freedom to choose any components they desire, as it supports the latest standards such as E-ATX and dual PSUs.

5.0 out of 5 stars fantastic, February 17, 2009
By David Wilson (Northville, MI United States) - See all my reviews
(REAL NAME)   
I've built maybe eight or nine PCs over the years, and previously favored Addtronics full or server tower cases. I like lots of room in a case so it's easy to work in, there's room for anything I might ever want to add, and there's plenty of space for good air flow. I thought those were excellent cases, but moving up to the ATCS 840 is like jumping from a 1939 pickup truck to a late model luxury SUV. Every detail of the layout and construction of this case demonstrates superb engineering. The immense 230mm fans move a ton of air, but do it while spinning far more slowly than smaller fans have to. That means little noise, and what there is is much lower pitched and unobtrusive. Just one of the engineering details is nice, easily removable, easy to clean filters for each intake fan. I could go on and on, but you can find a number of extensive reviews with large numbers of closeup photos online. Just Google for "ATCS 840 review". All the sites catering to serious builders and overclockers have reviews of this case, simply because it's one of the best to come along in quite a while. The only other brand with build quality to match this case would be Lian Li, and you should see what some of those cost. One last comment: if you're an adult who doesn't want a case that looks like it was designed to appeal to 14 year-olds, you will appreciate the clean elegant style of this case. I can tell you that it looks even better in the flesh than it does in the photos.

5.0 out of 5 stars Best case on the market!, February 4, 2009
This case not only looks incredible, but also is perfect for building a top of the line PC. It has plenty of room for expansion later and the build quality is second to none.

4.0 out of 5 stars This is a good case, June 20, 2009

THIS IS A GOOD CASE. I HAVE TWO OF THEM.

The good:

It's roomy. It's light. The documentation is good. It is even written in what appears to me to be passably literate English. Be sure to pay attention to the pictures in the manual, especially the one showing how to properly remove the front bezel. They clearly show the proper method and it's easy as can be!

If you're a water cooling fan you can replace the two stock 230mm top fans with three 120mm fans and a 3x120mm radiator without having to modify the case in any way. Very good!

Please note that none of the not so good points below have made me seriously regret purchasing this case (I have purchased more than one BTW). Personally I've never found a perfect case. I pretty much take the good points for granted. I'm good at finding faults though, so here goes in case any of these might bother you.


The not so good:

Both side panels are thin and lack mass so they end up vibrating like drum heads and amplifying otherwise small innocuous internal vibrations (such as from a typical graphics card fan) into big annoying loud noises.

Any sort of dirt or even a minor scuff on the black brushed aluminum case finish shows up badly and can only be properly cleaned off (without making it look even worse) by using a lint free cloth and wiping with the grain.

Both bottom air intakes are blocked when the case is placed on carpeting, but especially the middle bottom air intake (because its filter is on the outside bottom of the case and the case floor is inexplicably molded a little extra far downwards there as well). That could be bad news for your power supply if you mount your power supply on the bottom, it has a bottom fan and you face it downwards.

Placing a fan on the optional middle bottom air intake makes it impossible to remove the filter from the rear bottom air intake without first removing the optional middle air intake.

The forward top fan steals cool air from inside the case and exhausts it prematurely before it has had a chance to cool anything inside the case. Solution is to not hook up the forward top fan.

The two fans in the top of case "beat" against one another like the props in a propeller driven aircraft, causing excess noise that comes and goes in harsh low toned "waves." Solution is to not hook up the forward top fan.

If you don't hook up the forward top fan, then the rear top fan just pulls cool air in from the forward top fan grill rather than exhausting hot air from inside the case. Solution is to cover over the forward top fan grill. Makes one wonder why that forward top fan is even there...

The motherboard tray hole for the 8-pin motherboard power connector is not in the proper position for every LGA1366 (Core I7) motherboard that I've ever seen.

The blue power and hard drive LEDs are blindingly bright. They light up the whole room at night. The blinking of the power LED can become very annoying when the system is in sleep mode at night if it's in your bedroom.

The four front (top) USB ports are placed too close together to permit all four to actually be used at once in any likely real world situation that would cause you to want to use the front ports rather than the rear ports on your motherboard.

Other thoughts:

A somewhat amusing (to me) observation is that front 230mm intake fan seems to expend about as much energy cooling off the solid aluminum front face plate in front of it as it does cooling the 3.5 inch disk drives behind it.
