Here are some numbers for you to chew on. These are raw estimates based on what little information we have.

• 1 die is 1.9GH/s
• 24 die per board for a total of 45.6 GH/s
• 96 boards per Miner: 4377.6 GH/s and 28U of rack space

Based on these numbers we can extrapolate the following...

• 1,292,000 GH/s is roughly 680,000 die @1.9GH/s
• Each "Miner" requires 2304 total die
• 680,000 / 2304 is roughly 295 "Miners"

Assuming due to cable lengths etc that 1 "Miner" per rack you are looking at 295 racks based on these calculations. You can then adjust the per rack cost; but for sake of discussion I've listed $200-$400 as the per rack/month cost.

295 Racks @ $200-$400 per Rack
$59,000 - $118,000 per Month

Assuming 12 month contract that's $708,000 - $1,416,000.

Now you can adjust these numbers any which way you want... but based on that and a 'Total Fixed Costs - $1,340,000' I can tell you with some certainty that rack space was not included in those estimates.
