That looks like a really nice system as well.
One thing to note, the Gabu system is 1/2 depth, letting you put 14 GPUs in 8U of a standard 4 post rack (or you could use 2 two post racks).

This really only matters if you want to maximize your density and have control over your space (or are in a space without cold isle/hot isle separation, pretty common in a lot of locations). If you had control of your space you could have 2 cold isles and have a warm vent directly out the top.
Also, I would want to test the thermals on the 4U system. It looks like it will be very hard to push a large volume of air through the back of that system once two power supplies are installed (even with six 120mm fans).
The Gabu system has six 140mm fans and lets the GPUs vent directly out the back of the chassis. This conforms with standard GPU designs and should greatly increase airflow.
In all cases its really hard to say what will happen without comparative testing.

Would this 7GPU, 8U rack mount chassis work for your application?

Looks nice, but too pricey. You could get two of these for the same cost:

and put 12 GPUs in 8U of rack space, instead of just 7...

Here in the Netherlands that gorgeous case EricKennedy posted, would sadly be rejected for placement in a rack (hosted in a datacenter)
Rules apply besides hight and width.
But in the end I guess it all comes down to how much space you are willing to buy and the percentage of occupation at the given datacenter.
Furthermore, wouldn't the amount of air pressure needed to keep things cool enough, (is there any way to calculate this given the OP's demands?) destroy the fans on the cards?

That would work for a lot of open air people. There is nothing between the gpus to create any kind of pressure. If I use non-reference in that case I would be sucking air out from the intake fans on the cards, If I use reference I would be blowing from a strong fan to a week fan and sucking untouched air above and around the GPU's
I think I'll start selling my own for $150 + shipping in the US
I might be able to get it down to $100 depending on GPU count and mounts.

I'm in the process of producing 4U cases with the help of a local factory.
6 GPU, exhaust fans, 2 PSU, Mobo small format (like the H81 PRO BTC)
Here are the prototype specs :
Initial version with 5 GPUs and 2 PSU on the front
I should have the second prototype (6 GPU, rear PSU + option dual PSU) soon.
Please tell me if you could be interested.
Only problem is I'm in Europe, so shipping could be a problem.

It's been several years. I'm in no rush to expect someone to actually pull through and make this case. Besides I have plenty of room for 3 card PC cased rigs.
As long as you use positive pressure for reference and negative pressure for non reference and cool the backs of the cards it's fine.
I gave up for now 
Sweet science, I've been dreaming of a case like this. Please tell me you made them and are selling them. If so, I would like to place an order.
Calling you in a few.
OK, Here's the latest update with I think is what the OP wanted.
The cards can be moved from side to side with any amount of cards kind of like an open rack.
1 PS (although a second can be added).
4 80mm front fans, 3 120mm mid fans and 3 120mm rear fan in removable tray.

Need to get more info from the OP on the rear card support.

I'd still like to see the specs in the op
Specifically card mounts built in to run the cards with no PCI brackets and adjustable mounts to evenly space 3-6 GPUs.

AHHHHH....So you want a back that is completely open and you can slide the cards from side to side.
And a rear support that does the same. amiright?
Correct. I want to run 2-4 High High End cards or 4-6 mid range cards.
If 10 of these go into a rack It'll hit 10Kw+ per rack pretty quick so some space for adjustment is needed. Also there is a need for different spacing for future cards and systems.
I think you could fit 8 GPU in a 4u case with a bit of creative thinking 
( 2 systems of 4 cards )
my Skype is zack.clark4 if you want to talk about it
Edit also it would be worth considering going 8u and running 4 systems of 4 cards each as you could use the space a lot better

The center fans can pull air from the front or thru vent slots on the sides.
With everything closed up all the air will pass thru the GPU's and slots between the GPU's.
The front and rear can be turned into swiss cheese to get air in as well.

I like it! Dumb question, tho: which end are you referring to when you say "front" and "rear"? I kind of assumed that the PSUs and MB connectors would be at the front, and the PSUs would blow the hot air out the back, but your wording makes me not sure.
So for the 4U version, you would have everything the same as pictured, except:
-GPUs would be centered vertically, to allow for riser depth on the bottom, and PSU power plugs on the top.
-GPU backplate would be swiss cheese mesh, to allow for airflow.
-3 center fans would be upgraded to 140mm sizes. Will these be too tall for proper cable management, with risers below, and PCIe power above?
-Most of the metal case on the front (between PSUs and MB) and sides (before the fans) would be vented swiss cheese.
That actually sounds perfect. How much are you looking to charge?
Here is a updated version. Moved the PS to the bottom for easier MB access.
1. GPU'S are centered. Reversed PS and MB (you can flip the front plate to reverse it again).
2. Back plate is swiss cheesed I still have to add vents to the front and sides.
3. Right now the fans are 120mm and I added slots below the fans for wire control.
4. Swiss cheese incomming!!!!
5. I still have to add GPU rear support, Power/Reset switches
Once all the updates are done I should have a more exact price, But I'm looking to make it modular I.E. Rear Plate for 4 or 5 cards, 1/2/3 PS's, and just about anything else you can think of.

Please post any more ideas. I'll try to get in what I can.

It also looks like you could put a large fan between the PSU's on the front though it would have to be a hell of a high pressure high cfm fan to supply the three 120-140's in the center so open air may be better.
Those PSU's should exhale onto the GPUs or have a vent to push the air above or below the gpu's
Those PSU's should exhale onto the GPUs or have a vent to push the air above or below the gpu's
All of those thing can be done, or at least most of them. If you are using 120mm server fans they flow about 100cfm each! The center fans can pull air from the front or thru vent slots on the sides.
With everything closed up all the air will pass thru the GPU's and slots between the GPU's.
The front and rear can be turned into swiss cheese to get air in as well.
Do you really need more then 300cfm? I'm running 6 290x's with a 1600w + 850w power supplies and have no problems with temps.
A 5 min phone call can solve all the issues.
