Well, no worries about testing it for WCing just on my behalf...

But I might ask that you be sure to include some photos of the inside view of the top 3x120 fan mounts and one or two under that mesh screen! Some of the pre-launch leaks had more useful photos than many of these short, quickie reviews!

Comment from jmke @ 2008/02/25

I'm testing the case with my reference C2D/8800GTX setup, but I'm no fan of water cooling, so don't get your hopes up

overall I'm liking the "S" better for better space management and better expandability with the spare 5.25" bays. More on all this later

Comment from Kougar @ 2008/02/25

Guys, you both are agreeing with what I said above and in agreement with each other...

Motherbound grounds to case via screws, case grounds via PSU housing, PSU housing grounds to AC out ground line.

Bit-tech had 12 photos in their review, several of which were not useful... 5 pages (3, if ignoring the packaging and strange MB issue) and a few photos does not a review make. Did not even measure HDD temps! Did ANYONE attempt to use watercooling with this case, instead of just saying it makes a great WCing case?

Comment from jmke @ 2008/02/24

Tech station != case, look at what material is used

Comment from geoffrey @ 2008/02/24

The case is connected to the mainboard via screws, via the mainboard 0V line the case is connected to the DC 0V line comming out of your PSU, and the DC 0V line is simply connected to AC ground. It is, more or less, grounded. At least, that's what my multimeter is telling me

Comment from jmke @ 2008/02/24

that's in case the system is inside an enclosure, the tech station PSU is not in contact with any metal

Comment from geoffrey @ 2008/02/24

Very unusual as the AC ground is mostly connected to the DC 0V line, your mainboard is 'grounded' via the screws it is being installed with.

Comment from Kougar @ 2008/02/24

Another point that should be made is the tech station doesn't ground anything. With a PC case, everything is grounded so you can touch the case before working on anything in the PC, although I guess you can touch the PSU directly for the same effect. Still, I'd worry about brushing against something with a sleeve and shorting it. And while usually not a problem on high quality motherboards, I've read about cheap ones requiring grounding to the case to work properly!

I dunno about you but my DVD drives sound rather loud to me, NB fan on one of my boards is also excessively loud. Ignoring the rest of its faults, my P180 does a great job muffling those along with anything else I decide to use in it.

Back on topic however... are there any reviews that actually USE watercooling for the Cosmos S? Not even Bittech's review photographs the possible tri-radiator mount... if the case is perfect for watercoolers then I'd certainly like to see at least one review using watercooling.

Comment from jmke @ 2008/02/23

but you can agree that a case is more useful for the general public

Comment from Faiakes @ 2008/02/23

No kids, pets, wife.
Drinks don't get too close either and when they do only bottles are aloud, not glasses.

The thing is hardly anyone comes close to my PC, so it is safe in that respect.

Comment from geoffrey @ 2008/02/23

Every electronic device in the consumer market comes with a housing, case, just to protect them. I know, I've been caseless on my phase change cooled setup for quite a long time, but even the smallest accident can quickly turn your pc into dead silicium. You have drinks around your pc I presume? Kids nearby? Animals? A wife that cleans the house

I always double check my open air configs before going live, you just never know

Safety aside, a well designed case looks a lot better then an open test bench.

Comment from Faiakes @ 2008/02/23

You mean modify the existing one?

different PCs cases in different houses, both in places where room is dusted/vacuumed/cleaned every week!

Now a case without dust filters, left to its own for several months (years?) will end up like this:

???

Comment from jmke @ 2008/02/22

Make A custom bracket which makes 120mm hover over mobo

btw: as you see the station has fan cooling for mainboard and HDD!

Comment from Faiakes @ 2008/02/22

That is the most recent model you have there.

I have the first one

The position of the fan is not satisfying though.

P.S. I have the mobo on the top shelf though.

Comment from jmke @ 2008/02/22

would rather place/install a large <1000rpm 120mm+ fan somewhere, blowing air onto the mainboard, will provide better performance/noise
doesn't the Tech Station have fan mounts?

Comment from Faiakes @ 2008/02/22

I do have the Ultra-120.
You reckon I should invest in a couple of Antec Spot cool fans?

Comment from jmke @ 2008/02/22

depends on your CPU cooling really, if it blows down onto the mainboard (XP-120 style) there is no need for extra cooling, if it's a tower cooler (Ultra-120 style) the mobo heatpipe cooling will not get airflow, no cooling

That is the main cooling that concerns me.

Really? You reckon I should add extra coolers over the southbridge, despite it being cooled with heatpipes?

I agree about the HDD. Mine sits in a Cooldrive.

Comment from jmke @ 2008/02/22

not saying you should change, but saying open testbed cools better with same amount of active cooling is wrong

yes active CPU and GPU cooling outside a case will be better, but at the cost of higher noise and you need to add fans to cool down other components like chipsets, HDD, etc

Comment from Faiakes @ 2008/02/22

Portability is not my concern at all.

I think my setup is very safe. (obviously not AS safe as if in a case but insignificantly less safe).

I just can't agree on the cooling.

Noise, maybe. However, I tend to buy coolers stuff after carefully reading your noise/performace guides

Dirtier quicker? Yes. Significantly so? No.

------------
What can I say. I am a bit stubborn in my opinions.

Comment from jmke @ 2008/02/22

One Single 120mm one box, in-take hole at bottom of front case, exhaust near top of case. Airflows from bottom over HDDs, passes over GFX area, mounts to CPU area, is exhausted near the rear.

One single case fan at the rear, no active in-take, dustfilter at in-take. Closed sidepanel with no holes. This WILL work in practically all cases I've tested, no need for "wind tunnel" as I think you refer to an actual tunnel inside the case. It can help, but it's not needed.

house is clean, brand new here, not particularly dusty, but open setup does get dirtier quicker. The only moment I would consider an open testbed is for motherboard testing, to easily swap out components. That's it.

My testbed was also on a desk; all in all if you don't swap mobo's every week, a case is vastly superior for safety, noise, cooling and portability

It must be your dusty house then, that is the fault (personal attack = ad hominem

). I can't notice anything dust-wise after a week.
My setup sits on my desk, I have no pets, I vacuum (fairly) often.

Absolutely nothing over my setup. Of course, it makes sense not to have an open setup under something else.

also the reason why INSIDE a case you can enjoy PASSIVE cooling for CPU/GFX with one low noise exhaust fan. Now install that system outside a case and your CPU/GFX will overheat within minutes. Inside a case the ideal airflow path FRONT >>> BACK is designed to cool down the components inside, northbridge, CPU, GFX... and don't forget HARD DRIVES, without active cooling (no airflow) these will be 50+°C.

Oh I'm well aware of the benefits of wind-tunnels. My question to you is: how many cases do you know of that can, patently, achieve a wind-tunnel effect?
Most are simply a box, where you can attach fans and your components.
If there any that do approach a wind-tunnel effect, they cost so much that it's not worth it. You best be spending that money on a better graphics card.

I have never kicked or even bumped into my open case setup in 2 years. It seats at the corner of my large desk (with the wall right behind it, too).
I haven't even come close to bumping into it. Good design. That's all I'm going to say

You mean several 120mm fans, and now there are 140mm and even larger. Add stupid lights, and other gimmicky paraphernalia for all which you need extra cables running inside the PC, further preventing airflow (with the exception of the few expensive cases that have accounted for this).

You don't actually need an HSPC Tech station. I have one simply because it reduces the footprint of my setup. You can easily dedicate a few shelves for your setup.

With 1x120mm exhaust fan you can cool the whole inside of the PC with active airflow. You'll need more than 1 fan to cool all your components on an open testbed.

But they do make the PC hotter.
Heat cannot escape a case as easily as it can in an no-case setup.
Thus you have component fans running faster and louder.

OK, that was a satisfying amount of typing, I must say.

Case?

You must have children in the house jmke.
I have long given up on the notion of a case. Not worth it. I use an HSPC Tech station and it keeps everything very neat indeed.

Comment from jmke @ 2008/02/22

The new Coolermaster Cosmos -S- is the next PC Case in the Technic3D Editorship. See you in the following Review which qualities the High-End Gaming Tower with a new Cooling concept (200mm Fan) and many Features presents. Better than the Cosmos 1000?

Comment from jmke @ 2008/02/22

A big tower, who is made to cool your PC. Let's see how this one works.
http://www.cowcotland.com/articles/2...-cosmos-s.html

Comment from jmke @ 2008/02/22

The finish on the Cosmos S looks good, with a black/gunmetal color combination and a variety of textures from steel mesh to brushed aluminum to glossy plastic. I love the look of an aluminum case inside, rather than cheap, painted steel. Unfortunately there's no side window on the Cosmos to show that off. The abundant use of mesh on the front and side panel does allow light to shine through, although only one led fan is included. If you have a noisy chipset or CPU fan it's going to seem louder because of the mesh, but the included fans are all very quiet, even running at full speed. I had no heat related issues the entire time I was testing, and I do keep my computer running F@H 24/7 so that says a lot about how cool the case stays.

http://www.ocia.net/reviews/cosmoss/page1.shtml

The side panels of the Cooler Master Cosmos S are easy to remove and require no tools. To remove either side panel all you need to do is press an eject button on the back of the case.
The panels pop off the sides and are easy to remove. Inside the case the drive bays are tool less as well. The same locking rails are used in the Cooler Master Cosmos S that owners of the Cosmos are familiar with.

http://www.i4u.com/full-review-386.html

The Cooler Master Cosmos S is an attractive and sleek case that looks even better than the standard Cosmos, holding its own in the higher end of the market when it comes to look. If the Antec P182 is just a little too plain for your tastes then the Cosmos S is an acceptable compromise between that and a Cooler Master Stacker 830 Custom.

Looking at the Cosmos as a whole, it’s clear to see that the re-design has mainly focused on improving the look and accessibility of the chassis rather than making the fan cooling capabilities more powerful. That’s a mixed blessing obviously, but to us the benefits of this door-less and funkier design (that looks great in champagne grey) outweighs the unimproved fan cooling. It's also worth bearing in mind that the Cosmos S seems more aimed at watercoolers too – there’s room for a self contained radiator and so forth in the top.

Simply put, the Cosmos S isn’t the best case we’ve ever seen and there are other chassis’ out there that can outpunch it in most areas – but we like the overall aesthetic and, if you’re a watercooler, it could be seen as great value for money (especially compared to the Silverstone TJ-07). However, when you consider that the Cosmos S is 25 percent more than the original Cosmos and doesn’t improve cooling performance, you have to ask whether that extra cost is worth it. We love the thought that has gone into the case’s design and some will definitely see value in the improvements made—especially on the watercooling front—but it’s not for every man and his dog.

http://www.bit-tech.net/hardware/200...ter_cosmos_s/1

To get the system hot under the collar, both OCCT, ATITool (artifact scan) and HDTach (Long Bench) were run simultaneously for 30 minutes. As we can see from the graph above, the temperature inside the case rose by a total of 11c, which isn't too bad considering components such as the CPU and GPU were kicking out between 50-60°C of heat. In comparison, a recent test of Lian Li's V2000 chassis (under same conditions) saw a slightly larger increase of 15c. Good work Cooler Master.

http://www.overclock3d.net/reviews.p...osmos_s_case/1

Cooler Master really included many new features that I would expect to become a standard with high end computer cases, like the very cool touch sensor that replaced the standard power button. When building a high end computer system many user's focus on the internal components and not on the case, but with the Cosmos S arriving in March, the case should become a high priority.

http://www.bigbruin.com/2008/cosmos_1

In the world of computer cases, it seems that far too many do not stand out from the crowd. Cooler Master has decided to break tradition and create something special. With many features not seen before and full eATX compatibility, how well does the Cosmos S stand out?
