We’re currently investigating an issue related to the forum theme and styling that is impacting page layout and visual formatting. The problem has been identified, and we are actively working on a resolution. There is no impact to user data or functionality, this is strictly a front-end display issue. We’ll post an update once the fix has been deployed. Thanks for your patience while we get this sorted.
Finally, power supplies back on top...

they're better off on the bottom.
they get their own cooling zone.
pull cool air from outside the case and exhaust hot air out the back of the case never interrupting the airflow of the case itself.
that case is dumb because nvidia cards are made to be upside down.
and not enough hard drive bays.

The two fans on the bottom are actually exhausts, according to Corsair's logic: http://www.corsair.com/en/landing/600q

LOL NICE. It looks much better this way. It hurts my brain to look at it the other way, and I think they only did it for the sake of being different. I do like how the window is on the other side of the case as its normally on. My case sits to my left, so I can never see in the window.
I do like how you can look at the top of the graphics cards though. People love fancy GPU coolers, but they never get to see them once installed. I think this would be great if they left the PSU on the bottom, but flipped the MOBO upside down and moved it to the right side of the case. This way, you can see the top of the GPU's but not much else changes. The window would also be on the other side of the case since the IO panel would now be on the right. I would like something like this.

Looks great the way they show it, but where is all that exhaust going from the back and bottom? Most of us have our cases with their back toward a wall, so any air moving toward the back from bottom and back migrates up and if case is under a desk (like many are) across top of case, so if top is intake it is drawn back into system.

But the top isn't intake, the front is. What you're saying is basically this, since there are no intakes on the top:
Doesn't seem very likely... in fact, circulating warm air back into the intakes seems more likely with a standard layout where you have exhausts on the top.

My discription was not very good.
In that case i would worry more about the air from bottom exhaust coming back forwared. Their dotted lines are not at all what case airflow would look like. They look more like water sprayed out of a nozzle into open area. the radiator and fans in bottom are flowing air straight down. When it its the floor front fan airflow will spread sideways award front and back one will be sideways and back.
This heated air coming out the sides and back hits wall and turns up .. if there is a wall.
The heated air coming out the front will start to rise as soon as it starts slowing down. The front intake is sucking air in so more than likely will be pulling at least some of it back in the front.
As long as fans are in play and air is being guided by case, etc. the fans control direction of air .. fans and whatever is around or in it like cables, hdd cage, GPU etc. But without fans it warmer air is lighter and will rise all by itself. This is the heavier cool air moving to equalize pressure and lighter air doing the same. This is how passive cooling is done. Passive heating works the same way. A heating stove on ground floor will easily heat upstairs rooms if there are vents in ground floor ceiling / upstairs floor .. or an open stairway and open doors.

There is no intake area on top of the case. It's completely blocked (see Vortez).
Also I can't imagine the bottom of the case being even remotely an issue. Not only do most people not use 240mm AIOs - many will actually run the case without any floor fans, just like normal tower cases are often used without any top fans. But also, it's not like real cases are two dimensional cutoffs where the exhausted air can either go front or back. It'll dissipate all along the floor, only a very small slice of the exhausted air will go towards the front, and an even smaller portion will be circulated back in.

I like my HAF 932 which gives you the option to mount your ps on the top or bottom of the case. I have mine at the bottom with the fan drawing from the bottom of the case.
I drew what would be if a case has top vents / intakes.
Some of my arrows are as image is.
All arrows are to illustrate approximately how air flows compared to Corsair's lines that are a joke. At front they enter case at bottom (maybe below) fan / vent.
Warm air rising is not possilbe in a case with fans.
"Heat rises" is a common misconception. Heat radiates in all directions. The air it warms expands becoming lighter. This caused the warmed lighter air to rise and cooler heavier air to take it 's place. But is only happens when there are no other forces involved. Even a poor fan has many times the airflow ability then the warmed / expanded air.
This motherboard orientation makes supplying CPU cooler with cool air easier, but not as good for GPU coolers.
Normal motherboard orientation is better for GPU coolers but very hard to supply cool air to CPU cooler
Quarter turn orientation like SiverStone (which they have patent on) is better but requires case to have taller feet to allow good flow of air to bottom fans. Normal case feet only give about 18mm of bottom clearance while 2x 140mm intakes side by side need 40-50mm.
Here is illustration.

Your first reply did not suggest you were talking about a "what if" scenario, but that you actually thought it was possible to have top intakes in the 600Q. As such, your whole tangent about circulating hot air back in through the top is completely and utterly off topic.

I think you are splitting hairs a bit... hot air in circulation will still tend to rise no matter what, it's simple physics. It would be interesting (that's if someone hasn't already done it...) to put temp sensors in the bottom and top of a typical 2x GPU case and run some benches on it... just to see. Granted, a case with proper airflow should evacuate/turn over the air enough that the differences would be minor, but I'll bet you a generic case with only 1 or 2 fans... you would see a temp difference in the top vs bottom of the case.

Hardware Canucks reviewed it and found that a similar bottom PS standard layout Corsair case was 1c cooler. Not a huge difference, but the only advantage to this case seems to be that the window is on the opposite side of most cases.
It also lacks HD mounts and was awkward to work with. If I were looking for a case, I wouldn't even consider it.

Sorry, I made a mistake. Fact remains the airflow of this case is .. well there just isn't any. The top GPU has no direct cool air source at all. All intakes are below the level it exhaust it's heated air. Unless the GPU as reference blower cooling design they will be hard to cool.
A significant amount of heated air coming out the bottom will flow out around the front of case and the low pressure area created in front of the front intakes will tend to draw it toward them .. and back into case.
I am not guessing. It has taken half a lifetime of working with airflow and cooling to learn what I am saying .. and it is the kind of knowledge at most people do not have. Airflow is not an easy thing to predict or control without going the dedicated route like Apple did with the Power Mac.
But by all means believe what every you want.
Those that to listen to what I say are around on the computer forums. Ask them if I blow smoke or not. 😉

I agree, Corsair is not all they want us to think they are. The slap their logo on things and say they are "Corsair". Very little of it is.
