Have the same issues with investors. I currently have $150K ready to go and build-out. But, hardware is a joke right now and mining hardware (GPUs and high wattage PSUs) is going through a huge change with 13 PCIe slot MBs that look as if Windows will be able to recognize all 13.

Then, RX Vega, and mining specific cards around the corner, makes it hard to want to scale out with available 6-8 GPU RX 560/550 systems.

If there was a way to get a hold of 500 RX 570s right now, would have already started. 4 major US distributors can only get me 560s/550s in bulk, 570s maybe once a week 15 at a time. Still not enough to drag big money in right now.
