This is the array of ~140 Cairnsmore CM1 boards I built last summer.  The last time I had all of them hashing on a single pool they were pumping out around 115 GH/s.  Power demand is 6.5 kW, not including cooling.  I've moved them to a better location for summer, which is why I'm comfortable posting now

When I saw Skyfall I laughed at the lame crypto gear the movie's villian had.   Grin

I'd like to give a little shout out of thanks to all the folks at BFL and especially Inaba!  Without you this would never have been as profitable as it is today.  How you might ask?  Well:

  • They took millions in preorder money that otherwise would have been spent on hashpower that exists and competes with me off the market for nearly a year now, and continue to do so today
  • They scared lots of other folks away from making the investment I did, since it was obviously a money loser when they would ship in October
  • They are so unbelievable incompetent, they still haven't shipped!  Meanwhile these babys are chunking out $600 / day
  • When they finally do ship, their incompetence means they won't ship much and it will be many, many months before difficulty catches up with my electric bill
Thumbs up for the rigs, and for the BLF critics Cheesy
What is in those boxes??? Filters?

6" vent fans for exhaust.  The big aluminum things are mufflers to cut down on the intake noise and then the boxes are full of packing peanuts to kill the fan noise.

The exhaust provides about 1kW cooling, and then the white box between the shelves is a 4kW portable AC unit (the biggest you can run off a 15A circuit)
