This was my first one,

ran that baby in my bedroom which is in the loft/attic for just over 1 month, until the constant 35C in my room drove me to break out the toolkit and create this monstrosity,

God dammit and I won't even get to play BF3.
All I want to do is play BF3!

My laser/infrared thermometer says the exhaust is around 54C on my PSU's.

Yes, headless Ubuntu, works great.

Bios is flashed on both the 6990's & 5870's, I did have the 6990's sitting at 150hmz mem clock but I was worried it would cause damage so I upped them just in case.

I use phoenix with phatk 2.2, I think its mostly due to using a headless Linux setup. I have a Windows machine with a 5870 that only gets 445 @ 985 though its my daily workstation and has Aero and other crap enabled.

Here it is, I finally got around to getting the camera out.
This is my home made/bodged/ghetto cabinet I threw together one weekend.
It was an old glass cabinet I found in a skip which I ripped all the glass out apart from the door and replaced with some perspex I had lying around.
It cost me nothing to make, apart from buying the bathroom extractor fans.
4 x 5870's in the top & 2 x 6990's in the bottom.
I had some real trouble cutting that perspex with a jigsaw causing some splits and cracks (easily fixed with good old super glue) Until I discovered some spray grease and covered the blade and perspex to keep it cool while cutting.
And yes, that's a pair of my mothers tights I stole to use as air filters!
I salvaged an old computer case for the hdd bay & the power switches for the side. (it was such a pain leaning inside and using a piece of plastic to flip the switch)
You can't really see from the pictures but I used to use cardboard to wedge the 5870's apart for airflow, but I have upgraded to a length of meccano which works perfectly (hence the little meccano spanner)
This is running happily in my garage which is about 30m away from my house, I bought some old routers off ebay and set them up as access points to get internet in there.

Clocks:
5870 1: 985/300 458mhs 72C
5870 2: 940/300 437mhs 65C
5870 3: 940/300 437mhs 60C
5870 4: 940/300 437mhs 63C
6990 1: 920/600 413mhs 72C
6990 2: 920/600 413mhs 71C
6990 3: 920/600 413mhs 73C
6990 4: 920/600 413mhs 69C
All fans are at 85% and ambient room is around 25C

If you have $100k to throw around I would seriously reconsider spending it on mining rigs, you WILL have more coins buying directly now then those rigs will ever produce.
You need to sit down and work over all the numbers, this is a good start http://bitcointalk.org/?topic=7531.0

It's one of the guys from this forum, he posted the image in the hardware section a few weeks/months back.

Is using a credit card out of the question to help you through this situation?

Beta is sometime in September.

It just keeps getting better and better! 

6A is fine for what I need here in the UK with our 230v.
But yes, at the end of the day you get what you pay for and at £35 this is really the bottom end of things.
Have a look around ebay, you can usually pick them up second hand for decent prices from data centre clearances.

Sounds like you want to be using an IP remote power switch, similar to what most data centres use.
I'm using this one in my garage: http://www.openxtra.co.uk/p/usb-net-power-8800uk and it works really well for its cheap price.

I don't know of a way to make setxkbmap changes permanent but a quick fix would be to have "setxkbmap fr" in a simple bash script load on system boot.

Still looking

Not any more, they were stable for the 3 hours or so that I tested them and I raised the clocks to 600 just in case. I ran them again a few days later when we had some really hot weather at 150 for around 7 hours per day for 4 days and they seemed to be ok.
Something is nagging in the back of my mind about running them at 150 though and it makes me feel uneasy.

Don't give up, is the card new? It could be faulty and you might want to get it exchanged if possible.
