Small idea, try just use cardboard( to test it) and close your box up a bit better. So the only real airflow is the fans. im thinking the top fans will make a bit of a vacuum and pull the air out while the side fans will be building up pressure. At the moment, there is just too many holes so they are pulling a good bit of air that is just sitting around the edges, not from between the cards. Basically make some pressure in there as i don't think the fans are quite working too well being so far from the heat with so many gaps. Either being closer, or making the case closed will have the side fans forcing the air in between the cards a bit more and out the top as its the only logical way to go.
Should not take you more that a hour with some scissors, tape and cardboard and you will know very quickly if it will help.
Wont hurt seeing as you have such a beaut of a case there.

That is some serious-looking hardware!
Thanks guys! 
Case work looks fantastic!
Awesome build. I love the custom case.
I'm not expecting GPU mining to be profitable for much longer
No kidding....
Grinandbearit - I've got about $2500 in this one, not counting the stainless sheet or any labor/machine time going into making it. I did all that on my own, so I consider that free. My time is worthless I guess haha

If you had put that $2500 into Bitcoins a couple weeks ago when it declined so much...your would have doubled your money by today's price. Then you just sit and wait for Bitcoins to hit $500 each...or more...if you firmly believe it will. Think of the babysitting you do with your rig...Bitcoins in a wallet require no commitment. 90% silver or 1/10th gold coins don't either. Perfect time to buy precious metals is now. Mining seems to be a humongous waste of time.
You'd probably be right, but building this rig was pretty fun and I don't much mind babysitting it. Heck, that's mostly what my job consists of any more, babysitting a bunch of computers lol. One more, once I get it going good, shouldn't be much of a burden. I also want to make myself known as a custom computer case manufacturer, and what better way than building my own functioning rigs? (I've got more in the works too, including a 3630k/firepro v5900/64! Gb)
So you'd be right, I wouldn't really recommend anyone invest in mining unless power is free and you don't mind switching to another cryptocurrency rather soon.
I'm still debating a preorder with BFL, but I'm not just handing my money over with no protection. Being as I'm so close I might be able to use local courts to my advantage if I needed to, but I'm going to talk with a lawyer or two about that first. I have a feeling if they wanted to they could hide all their assets from any civil litigation, but I'm no lawyer so I'll quit talking now haha..
Thanks for the comments guys!
Looks awesome!
Do we all agree that this rig at 3Gh/s would net about 55 Bitcoins in a year at a 2% difficulty per month increase?...according to the calculator I used.
So, an approx. $2500 investment would bring back about $7500 in a year at $136 price of Bitcoin at the time of this post?
Is this how the math should work?
A true Newbie question.....

can you share the link of the calculator?
Great setup!

Impressive machinery 
Mine are actually on two different motherboards. One unit has 3 cards and the other has 2. All are connected directly to the motherboards. Mine is just an open air setup with a good fan blowing across all 5 cards. I setup a script to monitor my card temps every 15 minutes and log them for me to keep track of, and none of them get over 72C. I've played around with the core/mem settings quite a bit on my cards and most of them are running at 1150/800, if I remember correctly (don't have access to my machine right now). Not sure how much is to gain, if anything from running Linux. I just used it because I like it, it's free, and I don't have a copy of Win7 laying around.
The card I've got in open air manages to stay around 75 degrees, but that's at 1175. I can't seem to get windows to take anything less than 1500 for a memory clock, I can try and set it in CGminer and I get a confirmation that the driver reported success or something, but it resets back to 1500 or never changes in the first place. I'm going to have to look into that a bit once the heat is under control!
I bought a bunch of off lease PCs a while back for work, a couple are just lying around as spares so I borrowed the refurbished keys. Don't tell Microsoft!
Degart - Thanks!
TriplD- I'm expecting this thing to pay for itself in a little over three months. I'm not expecting GPU mining to be profitable for much longer, either BFL will finally deliver or someone else will. Either way, my already insignificant % of network hash rate will become even more insignificant!
I'm thinking of preordering a few BFL bits too. Least I can physically drive over there and kick some butt if they don't deliver. Only like 20 minutes away from me!
Mxmz.in - Power is free for me as I'm running this thing at work. I manage all the computers across the shop so this one is just going to blend in. With as much power as we use (three phase too!) we get it pretty cheap anyway.
This thing managed to crank my living room temperature up to around 85 degrees in the three or four hours I had it going last night. NOT cool, at all! That alone is reason enough not to run it at home to me lol

how much money did you spend on it?

Good luck with that... Expect x10 to x30 in the next 12 month

WOW nice setup !
I'm assuming you spaced yours apart with riser cables right? Are you using the powered version? My motherboard has a sata plug that supposedly adds extra power to the pci-e bus. Won't even boot without it if you've got more than three cards in there. If I wanted to upgrade to a few extra cards would you recommend the powered versions? I wanted to try and run them all on the mobo, but since that isn't possible I might as well add more haha
Are you running the reference clock? If not what sort of clock are you running to get that hashrate? I'd be a bit dissapointed to learn that you were able to generate the same average per card hashrate as I do at a slower clock lol. I might just return these ghz editions and switch to reference cards.
Would I see a gain in hashrate moving to Linux? I assume that the gui kinda takes away from efficiency a bit, right?
Thanks for the post Mccminer!

Yea come to think of it 3mm is quite thick So I am still considering if I want to spend so much on mining. People are saying go this way or go that way quite confusing.
But yea riser's would do the job since your cards wont be squashed making it hard for the air to flow through them.
