Stealth rig at work. Only 1400 kh/s for now. A 7970 and a pair of 5850's, soon to be joined by a 7950. That stand is an old PictureTel unit I was given that I gutted.  Tons of room in these things and designed for cooling.  There's also a Logitec sub in the bottom compartment as the Unit's "Clark Kent" theme is my jukebox/workstation.

Nice design. But I hope you are not stealing your employer's electricity, that would be just asking for trouble...

My electrical usage is allowed. I just don't want expensive hardware hanging out in the open. I'm not going to build a farm at work, lol.  This is a test rig to check the viability of the whole thing.  Being as I'm there 6-7 days a week it made sense to put it where I am the most. I have a much larger installation pending for the house.

I did the very same thing at my work around a year or so back, it was great experience for the farm I'm running now.

It's a very good thing you've hid it, and if you haven't already I would not tell your coworkers what exactly it is you are doing. In a year, they may just be jealous haters, saying you've got preferential treatment...



Here is 1/3 of my farm that I've managed to get deployed so far. My rigs love the environment, it stays a steady 60 degrees or so, and my cards stay around 65-70c at the most.

There are 12 290's, 6 280x, and 6 7950 in this picture. Not shown are 12 more 290s I am "proving out" at home, as well as a few other misc cards.

I´ve got plenty of experience running stealth rig at work several months ago - I´ve been treated like malicious hacker and charged with industrial espionage and pasword breaking, when some coworker found my rig.. No fun at all

 Cheesy Cheesy Cheesy

That's hilarious! I've toyed with the idea of ditching a few USB miners around my office hooked up to Raspberry Pi, this was a few months ago. Never had the balls to do it though, work for a big company in a job I like and just not worth the risk of them launching an Agent Smith crew of IT guys on me...

pilotchup,

Golden 280X's? Or lazy 290's? Grin

If they're 290's, I gather you've got them tuned for efficiency/lower temps instead of all-out hashrate?

Sorry I didn't leave a comment with the picture. Posted it right as we were leaving the house.

They are indeed 290's. Just got them operational and was having a problem where GPU2 would report SICK/DEAD after 10 minutes of mining so I took the settings way down to see if that was the culprit. So yes, they are lazy 290's! Looking forward to tune them soon.


These are water cooled as well, it isn't that high performance of a water cooled system (since I didn't want to spend a ton of money in that), which is why the temps are in the 60s.

Therefore, that RPM you see is not fan RPM but my two pumps' RPM. I made a custom cable to connect the tach of my pumps to the sensor on the GPU that is for the fan. Then I wrote a program using cgminer API to auto-shutdown the computer if that RPM falls out of acceptable limits (aka pump failure).

Going to write a guide soon on how to get 6 R9 290s working, since I had a helluva time getting it to work. There really isn't much info out there on how to get that many working.

Cheers!

p.s. that is fastcoin solo mining, was just experimenting to see how solo mining works.

Just ordered a few more to fill out the hub (antminers)

Its basically a USB Fan fully sealed at the front so all the air goes down a 2 ltr coke bottle with the top and bottom sealed off

Basically made a homemade ghetto wind tunnel

Looks like a damn good idea to me.

One thing i got to say is there are some cool cooling ideas here,..

I am sure this has been asked before, so apologies in advance if it has, where did you get those risers? Stateside? Know of any eu suppliers?

The USB riser cables came from China directly, I ordered them in bulk. There's really only one or two suppliers, last I checked.

There are a few guys who sell them on the forum here, you may look around the marketplace a bit and get lucky and find a local seller.

Those multiplugs are a fire hazard if you're not careful how much you load onto them. I'd check how warm the cables feel. Wink

And on the "I built this myself", may I present a BFL single/25 that hashes at 48. :-)



Yep, that's 5 chips added on the right side. And yes, I had to build the whole 1 volt supply myself. To be honest, I'm actually kind of impressed with this one, details over in this thread.

https://bitcointalk.org/index.php?topic=424604.0

Maybe I should get a job building these. Or testing them; I seem to be good at figuring stuff out.

So my latest procrastination had several design requirements:

- Must ventilate most of its heat to the outside (hot Australian summer at the moment)
- Must not be audible from any part of the apartment (as declared by the minister of Finance and Tribal Warfare.) outside of the spare bedroom
- Must not burn down the place if some shitty PSU cable/connector catches on fire

But first, some history... The existing solution that worked for ~half a year for my CPU miners (Primecoin/Protoshares): I had installed most of the stuff under the home entertainment unit, complete with fan intake and ventilation duct (this was when I was single, can you tell?):

http://i.imgur.com/bhZUclP.jpg


http://i.imgur.com/lGFLb7a.jpg


http://i.imgur.com/zvjFqOy.jpg


At its height, there were 7 computers in there, ~500 watts of heat nicely ventilated outside. Ambient temps are often 30 deg C all day where I live so more heat from mining is not required...

Anyway, certain people found this setup in the living room unacceptable and a new solution that met the criteria above was created...

Mining box!

http://i.imgur.com/5LwchAJ.jpg


Home of the mining box

http://i.imgur.com/YN8jNaV.jpg


Since the first pics, some motherboards had died, other systems were repurposed. As a result, the mining box would house:

1x core 2 quad q6600, dual radeon 7790s
1x core 2 duo E8400, 1x radeon 5750
2x core 2 duo E7500, (CPU only)
16 port gigabit switch

Here is the power infrastructure, networking (including switch) hidden under a plane of glass. On the right are the two E7500's and in the middle is the E8400 and shitty old 5750 card:

http://i.imgur.com/EI7qYt6.jpg


The Q6600 and 2x 7790 placed on top of the glass which sits sort of diagonally:

http://i.imgur.com/5YP4hDO.jpg


As it turned out, it was very hard to cool this thing while keeping it more or less silent. Most of the things in the box were quiet, but most of the AC powered fans I had to ventilate it were too noisy. I finally tore this rotary vane (squirrel cage) fan out of an old portable air conditioner. I added a cord and switches for it. It has three motor winding taps and can run at 85, 155, or 185 watts (@230 volts). Unfortunately all of these were simply too loud. Even at the lowest fan speed it creates reverberations that can be heard from the other side of the apartment. The solution is to run it on the lowest setting, through a step down transformer that outputs @ 130 volts. This limits the total power consumption (and noise) to 28 watts. The clips on the side are to hold on the dust filter. The plastic lid placed on top of the CPU heatsink is to deflect some of the air coming down from the fan, which can make an annoying whistling noise:

http://i.imgur.com/pLjv8CD.jpg


The box is pressurized by the big fan, and hot air flows up through a duct to the window above:

http://i.imgur.com/nB1WvUj.jpg


Making the wooden window frame and getting the duct to stay in it was a huge pain in the ass. I finally settled on a ventilation fascia installed into the wood, which gave a point to secure the duct to. Its held in place with some reusable zipties and screws.

http://i.imgur.com/7GEIj6J.jpg


Unfortunately, as I discovered later on, making the fan silent by running it at lower RPMs reduced the flow rate too much and things were getting too hot. As a result the Auxiliary Air Accelerator(TM) was created for $9. I'll eventually cut out some metal at work that will make this duct connection and entire top of the box much neater.

http://i.imgur.com/RJedYNF.jpg


http://i.imgur.com/B32i1SX.jpg


The final setup as it probably will be left from now on:
*I changed the step-down transformer to a 1000 VA model so all of the motor speeds can be used if needed

http://i.imgur.com/WNOe5xJ.jpg


There is another two 7790's and a watercooled 6870 (display device) on the HTPC, now much lonelier without its CPU mining brethren:

http://i.imgur.com/55WOwDc.jpg


http://i.imgur.com/y9UZa2E.jpg


So numbers? The CPU mining across all of my systems makes about $8 revenue per day. Mining dogecoin across all my GPU makes about $20-22 revenue per day most day. Power cost per day @0.30 AUD/kWh is about $8 to $9. I have some outdated ASIC strapped to the cooling fans of my makeshift NAS pile which get about $0.15/day? ( Roll Eyes ):

http://i.imgur.com/3Zdtnyo.jpg


The end... for now...

Cables are very cold none of my cables run hot, today I will split up the rig and yes cable tie the shit out of those messy atx wires aha.

Also looking to mount everything in a spare server rack, Cheers
