So many turned-off miners everywhere. I don't understand why you people are not selling this turned-off hardware, there are places with some dirt-cheap electricity who will surely be interested, it's a shame all that hashing power to be off when it can be of use to the network. The electricity price and difficulty very, very likely will not go down enough for this hardware to be turned on again at their current locations, so selling is a gain for everyone, or I'm missing something?

Hmmmm?
What happened?

Why a n-vidia rig  ??

An Inert gas fire suppression system would ruin ROI for any Bitcoin mine but surely if you spent a few million on SP30's you'd buy a few $5 fire alarms and have a security guard?

I think it's an insurance scam but they forgot to buy any first.

You could fry an egg on top of an SP10 I certainty wouldn't put 2 on top of each other.

You'd think you'd invest in cable ties before investing in fire alarms, no?

The picture is from bobsag´s hosting facility, he therefore doesn´t own the majority of the shown miners.

It also looks like his thermal engineering isn´t optimised to the fullest extent, as there is a significant amount of unused space in those racks.

Humm  487 KW.  At .10 per KW his electric bill alone is 35K per month.  Making about 350 BTC per month. By December that number will be down to 150. Hope BTC doesn't go below $200. Not going to ROI.

"Mmmm hashrate" indeed...


Not mine.
QG

This is the picture of my miner which is hidden after the drawer set under my desk in office.
That is 160Gh per board, and no electricity expenses and internet expenses...

Probably solo mining farm

I can protect them from the sun so they would be cooler than inside a room, and in winter, middle part of terrace has roof so no problem and water doesnt get there, also i can protect them with something else.

Thing is its impossible to have 2 or more miners inside a room, so much hot....

Anyone know of any online cable management classes?

+1 yep that is what i'm doing with my jups...cept i'm not ever gona sell'em...they will mine til they give out to try and get as much coins from them as i can...

Man where ever i ask they say grindseed is not profitable anymore . IS it  ?
What coin do u mine with them ? I can get couple for 50$ each . Is it worth it ?

yer right it is a gamble...but i'd say its a really bad gamble...everything is exploding now with asic's...really nuffin ya can do cept buy coins...

The majority of the "different" cables are, I believe power cables, most of the cat5 cables are red with one rack of blue. But the black/red/yellow ones are breakouts from the server psu's

if you don't like it, don't look at it i love looking at that setup and wish i had it

Its not hard, work out how much power (energy) you are pulling out and then get the equivalent amount of cooling power.

Heres some ideas to get you going:

Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.

Most aircon units are measured in BTU's so I'll work in that unit.

Equipment BTU = Total wattage for all equipment x 3.5
Room Area BTU = Length (m) x Width (m) x 337
Lighting BTU = Total wattage for all lighting x 4.25

There seems to be no windows, or people working in there permanently so you can probably leave those calculations out.

Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU

So you need enough aircon cooling to handle that amount of heat.

I'd say on equipment alone you would need minimum 100KW or 350K BTU's of cooling

It only appears that you have two of them, thats max 50K BTU if you have the most powerful (25K BTU) wall-split units, so you would need 14 of them.
