Thats sounds really interesting. I can be interested in rent some power or put a rig in your farm (but here we can see the prices of components in Norway)
I'm planning on purchasing all of my components from Sweden (cheaper), I'll be able to buy parts from these sites tax-free. (-20% on the price). You can select this option by clicking "Exkl moms"

http://www.inet.se/kategori/168/amdCurrently the ratio between KR and USD is about 6,5:1
Basically a 6950 1GB will cost 233 USD, and a 6990 640 USD.
I wont order until I have a rather large (4-5 riggs) quantity, to make the shipping cost minimal per part.
