Chi11ed - Unfortunately water cooling isn't so simple with these cards as they deviate from the reference design. I've yet to find a full cover water block that fits this card! Of course I could always make a few, but I can't make radiators or pumps. If I can't keep these cool with air, I'll be moving to water 
Prelude - It's actually a waterjet table, though it did have a plasma cutter riding alongside for quite a while (the box to the left of the waterjet head.) Plasma cutting is a messy affair, and getting decent cuts in stainless comes with a pretty steep learning curve. To cut stainless without oxidizing the edge really bad you need a special mix of gas, I believe it's called H35, or 35% hydrogen remainder argon. Very hard to find and expensive! Nitrogen will leave a terrible black burr that's hard as a rock, no file will touch it
This case was made from 16 gauge 304 stainless sheet, a scrap piece I had around from some previous job. Most the stuff I do is for the food industry, so it's all stainless for me.
Miningdude - Thanks! I did try running them without the fan hoop in the way, with a 24" box fan to circulate air across everything and they still got quite hot unfortunately. Of course removing the fan hoop also means I can't spread the cards apart with the cool little flexible wire ties, so that might work if I put a little more time into it. But, with free electricity I'm not too worried
Wolfgod - Power supplies do work that way to a point, if you are loading the power supply a good bit under it's rated capacity it will not work as efficiently. You may be able to guess at your power draw, but the best way would be something like a kill-o-watt or inline power meter.
Miningdude - Here in Kansas and in an industrial park power runs about 8.5 cents a kilowatt! Luckily I don't even have to pay that
Buuuut, this thing is running in my office and it got HOT today! With the three hot cards choked down to 500mhz I still was only able to keep my mining going for about 6 hours. It literally decided to quit 6 minutes before I got home from work and I can't get Cgminer to start over RDC
My riser cables aren't marked as shipped yet either! I paid good money for US shipped cables! WTF!!
Thank you to everyone else for the nice comments on my case!
