Pictures of your mining rigs!

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 my little baby 



4x270x running at 1870 kh/s @ 700W

Seem good cooling solution, what is the temps to cards?

[EricKennedy]

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

My latest rig

• 6 x Asus R9 270 DC2 @ 1135/1500
  Gigabyte 990FX AM3
  2GB DDR3
  Sempron 145
  Corsair CX750 750W
  Fractal R2 750W
  Add2PSU
  6x x1->x16 powerd risers
  USB-stick with BAMT 1.4.1 "honeybee"

2940Kh/s @ 975W

[sQueeZer]

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.

That makes it a very good price/performance rig, what is the temps of the cards? Mind to share cgminer screen ?

Where did you bought those long usb cables, or they are 30 cm ones?

[febiz]

I tried pretty much all configurations and this one was the best by a good margin. The cards temperatures are between 60 and 67 °C, with fans on low settings (7V).

I'm giddy as a schoolboy. Just got all my USB Block Erupters set up and hashing. Just had to share this here.

you ordered from friedcat and already got them?

what are they plugged into?

FYI you are getting a ton of hardware errors

Did you seriously just quote a post from around a year ago to tell this person something they likely already know? 

Block eruptors make hardware errors when they are working, the percentage depends on the mining software used.

That is nice! Those 3 fans provide enough airflow when it's all closed up and in a rack?

Are you making those to sell? How much did it cost you?

All i see there are extra costs. The enclosures, the super expensive USB risers and the computer fans (while big ass box fans are like 25 bucks).

I highly prefer my way. Buy metal frame shelf, modify it and fit 10 rigs in it. All this for practically nothing.

[Analyticse]

Keep up the good work guys!

I see somebody is amused by my work..

Yeah this very nice

It's too early to tell, but it looks like airflow is enough.
I'll know more when I'll have 10 cases in one bay

Prototyping is very expensive, but I plan to make 100 pieces so at then end it should cost ~150€.
I'm not doing it primilary to sell, I have the need to build clean cases for data center hosting.

If you are really interested I could sell of course, but international shipping would be quite expensive (I'm in France).

You are right, these are extra costs (except the USB risers, not so expensive when you buy a lot).
This makes sense only to host in 19" racks.

I'm sharing for fun, not to tell this is the way people should build their rig.

Ok i was thinking you were trying to make them and sell them.

If i could build that for reasonable costs (like you probably) i would.

I'm getting ready to build my first open air rig, I've noticed one thing...none of these open air rigs appear to have a power button. How do you turn the unit on?

Nice work Eric - I work in a datacenter, and having professional looking machines in our racks is very important.  Best of luck to you!
