Cooler Master ATCS 840

Cooler Master ATCS 840

The first computer case that pops into your head when you say classic, luxury, or high end, would be a Lian-Li or Silverstone. Not anymore. Cooler Master has been in the market for over a decade. They run lines of power supplies, CPU coolers, and computer cases. Popular lines include the Stacker, Cosmos, and the CM690. They were very popular for modding. Cooler Master seemed to lack a classic looking/high end case, until now. Clan Team Xtreme has the honor to review this Full Tower Premium Chassis. They call it, the ATCS 840. (Active Thermal Convection System)


Packaging


When the box arrived, it had your “minor” damage that the delivery people tend to cause. Luckily Cooler Master noticed this and made sure to package the case very well. The box is reinforced with double corrugated cardboard. The chassis is wrapped in a plastic bag, with Styrofoam on each end of the case to protect the corners from dents, scrapes, and the tossing and turning that occurs while shipping. The ATCS 840 package design is just what you would expect with a normal case. It includes the usual black text with descriptions, graphics, etc. After removing the packaging from the case there was no dents, scratches, or abnormal marks. I was surprised!

Features

I will proceed onto the features and design of the case, which was a very pleasant spectacle.

Front View



Side View With Panel



Top Fans With Grill On



To take the grill off, you just need to remove the two top thumb screws, and proceed to pull it straight backwards.



Inside of case when arrived



Transversally Mounted Hard Drive Bays



Push Button 5.25” Bays



Front Fan View/HDD Fan Mount



Vented PCI Slots



Top Power Supply Bay/ Water Cooling Holes



Back View



I/O Panel: This is another innovative design from Cooler Master. When pushed in, the I/O ports are concealed. After pushed in, it pops up, revealing all of them, nice for those who want a clean looking case when not using headphones, USB, etc.



Cables For Front I/O



Motherboard Tray: So, whats so special about this? Well, Cooler Master was brilliant enough to use ball bearings, 96 total, on the motherboard tray. This allows for effortless, smooth, sliding when removing the tray, and sliding in too! This also is nice because it prevents metal-on-metal contact. Very handy tool!



Ball Bearings



Tray When Removed



Continuing on for those who would like to know the size of this case compared to another, I have a CM690 side by side with it. As you can see, it is much wider, thanks to the 230mm fan located on the front of the chassis.



Accessories : The black pieces of plastic are the mounts for a 120.3mm radiator if you decide to liquid cool. This replaces the 2 top fans. Also included are 6 large zip-ties. 5 of them are in the accessories box, and one is already mounted on the case. Also included are a handful of small zip-ties, screws for the motherboard, a motherboard speaker, a power supply stabilizer bracket (if used on top bay), and a CPU 8 pin extension if your power supply doesn't cut it for length. A fan grill for the air duct is also included.



Air Duct Installed



The manual shows detailed info on installation if you need help.










My one gripe is this, which may have been missed when on the line, but nonetheless, its there. The case is missing a rivet on the top corner, which is probably the worst place to be missing one.



Overall, this cases design is well thought out, from little things such as the thick aluminum frame construction, to the ball bearing motherboard tray. Besides the missing rivet, I couldn't see any real design flaws. Let’s get to construction.

Construction

Building with the ATCS 840 was the easiest computer that I've ever assembled. The removable tray made installing various parts simple. I didn't have to worry about cramming my hands inside the case, although without a tray, I couldn't see that being a problem since the immense amount of room that this case has.







I could've and should have hid the I/O cables better, but the main cables, such as the CPU, ATX, and video card connectors were tucked away nicely behind the tray, and then brought back out to their destination. The holes worked very well.

Final Thoughts

Well, there's so much about this case that makes it competitive with Lian-Li, and Silverstone. Evidence such as; the removable motherboard tray, high airflow with the 3 monstrous fans, and the all aluminum construction, show that Cooler Master is back in the game, and with a huge bang. This case offers more features than Lian-Li's offering, and possibly even the Silverstone. Don't count out Cooler Master next time when looking for a premium chassis. I know I won't!

The Verdict

Packaging: 9/10 Frags: Double corrugated cardboard, and superb protection make up for the colorless design

Style: 10/10 Frags: Cooler-Master has taken a new path with this beautiful chassis, aluminum finish looks great

Design: 10/10 Frags: All aluminum construction puts it into the luxury dept. spacious interior room, plus a semi-compact overall size that still fits under a desk

Features: 10/10 Frags: No questions asked, the sliding motherboard tray, high airflow fans, and pop up I/O port sets a new standard for high end cases

Price: 9 Frags: Offers more bang-for-buck than its Lian-Li/Silverstone competitors


This Case Receives a 9.6/10 which makes it Clan Team Xtreme Approved!

They do have great products, and I'm a proud owner, but their quality is mediocre compared to Lian-Li. Then again, they do come with a price tag.

[GregSG]

Just to check, how many fans are there in total?

And how many fans can u install? 120mm, 140mm, 230mm?

[Hennels]

Not a bad review mate.

Only one criticism. The logo on your pics are quite annoying and take the focus off the case. Perhaps just the one pic in the top corner?

Other than that

[SNiiPE_DoGG]

A true beauty of a case, inside and out. and a great review, you should check out making a DIY lightbox for your pics to make your review much more professional.

to bad it's still not big enough for me

[SlackerXL]

I wouldn't be so sure about that m8...
Their quality especially in their top alu series cases is excellent
at least ~90% of LLs imho...
and they do pay attention to user needs
thus implementing ιnnovative ideas quicker than others
And keep in mind that all those things come with a reasonable pricetag

i'd rather have CMs extras in case
(ball bearing removable tray, vented exterior pci brackets,
ready-to-use to radiator mount, socket holes on mobo tray, etc...)
instead of some diamond cut aluminum details for the same $$ on a LL case

but as i said
thats just my humble opinion

[LuckyNV]

can you fit a tall aircooler and then slide it in?

Just to check, how many fans are there in total?

And how many fans can u install? 120mm, 140mm, 230mm?

2x230mm top, 1x230mm front, 1x120mm rear

you can fit an additional 2x120mm on the HDD cage

[GregSG]

Oh thanks, but i was wondering if i could swap the 23cm cans for 12cm fans, and how many would i be able to swap?

[Duke-Nukem]

A really nice case! I love the "stainless" look of the polished aluminum. The features make this case an easy build from what I can see. Sorry about the watermark. I didn't think it was that bold. We'll tone it down more in the future. Getting a lightbox would be a good idea. We have different members doing the reviews for different products, so that might be a problem. Thank you to the Clan Team Xtreme crew who pulled this together for the midnight release. GOOD JOB!

[woffen]

If I understood it correctly you can change the 2 230mm fans in the roof to 3 120mm fans. You can also add a fan in the bottom of the case

[avddreamr]

I would imagine that you can place a 3 x 140 mm radiator up there. Should be interesting. Althoguh I would of loved the option to have a side panel mesh area, to install some fans on the side, to exit on top.

An amazing return to form. I personally owned 3 Atcs cases, and I'm fairly certain that I will be purchasing this one.

[SNiiPE_DoGG]

I would imagine that you can place a 3 x 140 mm radiator up there.

assuming my math is right it wont work quite correctly:

120mm fans have holes which are 105mm apart along the square edge. 105/120 = .875

(230*2)*.875 = 402.5mm length from first fan screw to last fan screw

GTX 420 radiator is 417.5 first fan screw to last fan screw and is 460mm in total :\

[Riggs]

Case was a dream to work with guys! I love it! It'll be housing my stuff for years to come!

[Riggs]

2x230mm top, 1x230mm front, 1x120mm rear

Yes you can. I could put my CoolIT water cooler together on it with tray slid out.

A mesh side panel may have taken away from the classic design that Cooler Master was aiming for. But it probably will be an option sooner or later.

[soulesschild]

I'll be picking mine up tomorrow. Do you happen to know if you could remove one of the top bays to fit in a feser 480 quad rad?

[MINIz guy]

I don't believe any 4x120mm radiator will fit completely internally on either the HAF932 and ATCS 840. A 3x120mm radiator will fit, there are even screw holes for the radiators on the top.

Same here - still miss my brushed aluminum Pratetorian case. I see these have arrived at the Egg - so I'm working up my i7 build now.

Even if you remove (if possible) a 5.25mm bay? Or is width the problem?

[MINIz guy]

Even if you remove (if possible) a 5.25mm bay? Or is width the problem?

The fact is that even with mounting a 3x120mm fan/radiator setup, you are already going into the area of the top 5.25" bay. With thicker fans or radiators, you may even take up 2 5.25" bays.

So, no, width is not a problem.

[chouchou]

I just wish that more cases came with the interior painted. Yes , its a relatively easy process but I'm lazy!

[PaRn ssR]

Great case

I want one

[junkun13]

i want to see this case running on water

great review!

[LordEC911]

Same here - still miss my brushed aluminum Pratetorian case. I see these have arrived at the Egg - so I'm working up my i7 build now.

Much cheaper at other shops, you can get it for $250-$260 shipped compared to $310 shipped at the egg.

[BababooeyHTJ]

That case is massive! I want one.

[DavidNJ]

Do you have the dimensions of the upper fan area where a radiator would go...length, depth, width?

I have an idea for a custom shroud...
