Here's an example picture from an improvised Bitcoin mine that somebody just posted in the Hashfast thread

In case the picture above is removed: it shows rows of miners running with no cases but laid out on the rearranged office desks with chairs&cabinets removed. I wish I could find and post the pictures for the first data centers for Victoria's Secret (and associated clothing brands) which were assembled from desktop computers laid out in cafeteria and mini-cubicle call center locations in supposedly expensive downtown skyscrapers.

Again, while I don't have specific information about the locations mentioned here, I'm positive that there are great opportunities available for temporary, improvised locations. Just look and ask around.

I bet those kinds of mines are profitable only because the person doing the mining isn't paying the electricity bill. I consider that to be abuse of the spirit of the contract, and tantamount to theft.

In the case above, they're also using air conditioning, which means they're using an additional 30% or 40% just to keep them cooled.

Here's how we do it. There's 48 kW running in just that one rack, and we only stopped filling it because we ran out of SP30s. No A/C. Our fans use about 5% of the energy of our miners. We're hydroelectric powered, and our utility company is happy to sell us energy at under $0.03/kWh all day every day. Nobody is bothered by the noise, and no landlords or megacorporations are unwittingly footing our bill.

I know, the cables are a mess. We're still rearranging stuff.
