Topic: Project: Stealth Mining Rig (Read 9946 times)

It only took me 10 months, but I built a 10Ghash/s stealth miner. It draws less than 300W.

LOL

You pick out the details that are going to be the most difficult. That gif be highly relevant.

Just so I understand fully, your plan is now to design a custom computer case, build it, populate it with mining hardware and then sneak it into work and make it look like one of the regular servers? 

How will you remove it when you're done?  Just wait till after work hours and sneak it out again?

Please do keep us updated, I'm excited to see where this goes.

Your sketches look good, you probably just want intake fans at the end of the gpus pushing air in, outlets at the top would be perfect for the gigabyte windforce cards as they mostly exhaust upwards.

Ok Thanks everybody for replying to this thread.
The critics are also very welcome and I understand the implications and the ethical thoughts.
I also fully understand the the final outcome is really low for the risk (which is also pretty small, as there is no one else managing the server and no one else knowing what they are actually doing, no understanding about dns, dhcp, etc... so no nerds around).
But however, it is quiet an interesting project, and isnt it the little things that satisfy you.

So I am probably going to design a case from scratch made of light material and well-thought ventilation.

I will keep you updated on the case... if there is any interest.
And also once I put it in the room I will inform you :-)

So far - wish you a nice day everybody

It seems like every few weeks we get someone on here looking to steal electricity from their employer to mine Bitcoins.  Not only is this ethically wrong and also illegal, it will most likely get you fired.  And for what, a few measly bitcoins? 

People have been fired for this.  People have had their lives ruined by this.  Please think long and hard about the risk/reward ratio here.  Realistically, even with 4 7970s, you'll make about .1BTC a day (difficulty is going up, so this number will be going down, not staying constant).  So in a 30 day month, that's 3BTC (maximum).  The next month will be less, and so on.

Is risking losing your job really worth an extra $300 a month?  Wouldn't it be easier to just ask for a raise?   

Not to mention that what you're trying to do is infeasible anyway.  No way in hell you're gonna get 4x7970s properly cooled and quiet in a server enclosure.  Even if they're full tower ATX size cases, it's still gonna be tough.  On top of that, any given server will not have a big enough PSU to support those GPUs.  What are you gonna do, switch out the PSUs with beefier ones?  And most servers have 1 single PCI-E port if they even have any.  So are you going to install a second motherboard in the existing server enclosure to support your graphics cards?  Impossible to fit. 

The hardware isn't there to do what you want to do, and you'll get fired in the end anyway. 

Think about this: you're looking at a spending over $1000 in hardware to try and scam your employer.  Does that sound like a good idea?  Does that sound like it will end well?

But if you do go through with it and manage to pull it off, keep us updated, because mining rig setups are interesting.

Yeah it would probably be best to get ask; better to be asking for permission rather than forgiveness

Yeah just be carefull mate. I read somewhere that someone at an IT company just got busted for doing something like this. Just saying. Best of luck to you though if you know what your doing!

Looks powerful :-)

Since you say noise isn't an issue; Just get two Delta TFB1212GHE on the intake and either tape over any airholes that are before the area in the GPUs are located, or make a nice duct with some plastic folders and electrical tape.

They'll be plenty cool enough if you're replacing the entire volume of the case every second.



To give you an idea of the power: it can propell itself along quite easily

You will never earn back your investment if you plop down $1,100 for a ModMiner (including shipping). Hardware break-even point is 337 days, and that doesn't include a network that is massively growing. The network could double, and your break-even point shifts to almost 3 years. A FPGA is the worst thing you could do right now.

ModMiner Quad is legit.

840mhash @ only 40 watts, 1069$

Where do I get those FCPGA's?

If not taking the moral question in consideration...

* Watercooled rigg = to expensive, atleast 100$ per card
* Lots of fans in combination with stock cooled cards = to much noice
* ASICS = no where to be found atm

Which leaves u to FCPGA mining, higher $/ Kh/s but consumes alot less power = less heat = less noice = less likely to be revealed.
Buy a bunch of them and place them inside a ATX chassie, and voila!

Yea, it isn't always better to ask forgiveness than permission, especially after cgminer crashes your company dns server in the middle of the work day 

It's probably not a good idea to mine with any mission critical servers.  It would be better to build your own stealth rig and host it at the same facility, with management's permission of course.

Soooo by "server" you don't really mean "server". You mean you grabbed your 6 year old Dell and threw Linux on it, and now it's your "dedicated email server"? And now you want to throw a few 7950s in them, and hope your boss doesn't notice? Nice.

Openly Admitting:
So I got a couple of servers @work (smtp, dns, etc). I want to extend the services those computers do to mining.
I also do not want anybody get suspicious about them having 3-4 GPU's sitting inside. So I want to make them look normal and mine with them.

I wondered that myself but wasn't sure about asking.  Especially since it can be as loud as needed, why is 'stealth' such an issue?  Seems contradictory, but to each his (or her) own
