Hey if you wanna have a go, I've got all the parts except the video cards... Just name your price.
let me get it straight, you have managed to get it working at 11 GPUs?
if so then expoanding the rest of the way should be simple.
If it works with 11 GPUs i am willing to buy it, but shipping is international, get a quote and i will pay.
For simplicity i can pay in BTC.
