Here's our 7 card 290x monster rig from Ninja Group Buy #4.  It's a rack mounted tray design meant for deployment into a data center cabinet.

Incredibly impressive arms race.  Could spend all day on this thread alone checking out all the jewelry.  Old news I know, but this setup is pretty impressive as well:  http://dealbook.nytimes.com/2013/12/21/into-the-bitcoin-mines/?_php=true&_type=blogs&_r=0

What are the temps like with so little airflow between the cards?

Tips? 1crazy8pMqgwJ7tX7ZPZmyPwFbc6xZKM9

Since I saw that 5850 rig I figured I should show my ghetto rig





Pushing 1.1Mh/s the whole rig cost me ~$500

Very interesting. I'm also working on a 4U rackable case for data center hosting, but I've doubts about temp and ventilation. I'll post pics of our prototype tomorrow.

Could you please post hash rate and temperature, when multiple cases are enclosed in a 19" rack?

With a box fan sitting on top of the cards they stay around 75C, pulling 930kh/s each.  They are scheduled to be installed into our rack later this week, and we'll sort out their airflow/cooling situation then.  This one is going on the bottom rack of one of our cabinets; with 2 airtiles popped right in front of it.  If I were to do a full cabinet worth I would go with max 6 per 4/5U case, enclose them and pressurize the case with high CFM server fans.  This is all highly experimental of course (and fun!). I'll post an update later this week after they move to their permanent home.

With such easy access to the needed power, is there any particular reason you aren't using server power supplies for the cards?

If you ever need help with custom rackmount cases, let me know  Grin

Please DO NOT send me private messages asking for help setting up GPU miners. I will not respond!!!

We had the corsair 1200's on hand; we've been looking at server power supplies and having some custom cables made up to provide a ton of pci-e plugs. I found some on taobao done up like that and they are very cost effective.

Pretty much the same as me, I picked up a few big EVGA supplies before they got expensive, luckily. Been working on putting together the server supplies lately, about tired of crimping after one rigs worth of cables already. I've been de-pinning the molex to pci-e adapters that come with GPUs, so the cost is in wire and crimp terminals. Pretty cheap, in other words. 

Just wish I knew a faster way to do it  Grin

2 x similar rigs of 6 x 280X's

Need a lot of tuning yet but haven't had the time

Frames are off-the-shelf steel from Bunnings for $37ea =D They stack nicely... I can remove one frame to work on it, then stack them back, all without powering down the miners.

I've modified them slightly - only using one shelf, but added right-angle aluminium for the cards to sit on.

Here is our 19" 4U rackable rig prototype




We have 3x R9 290 and 2x R9 280X but it looks like they don't like to work together.
Testing with only the 290s, the ventilation was quite good and temperature was the same than in our open rigs (~90°).

We'll rewire with 5x R9 290 (the 1600W should be at its limit) and test how it goes.
We could also put the PSU near motherboard, and space the GPU a little bit more.

If it works then we'll be able to fit 10 rigs per 19" bay, and make a nice looking laser cut front panel for each case Smiley

Are you 100% sure it is drawing 950Watts for 2.9MH?

This sounds TOO good to be true

I belive the 270's "non-x" are great value right now, u can squeeze almost 500kh/s (475-490) from them for ½ price (210$ in Sweden with BF4) of the 280x (385$).
My kill a watt-adapter measure's values from 940-980W @ wall on 100% load. I downclocked the CPU and no connected fans.
