Here are the aluminum part used:


...and one more for the Power Supply section:


Worked on the motherboard section tonight. Screwing in the MB standoffs worked better than expected.


Really had a hard time drilling the holes since the top part of the frame interfered with the drill. In hindsight I should have turned it upside down and drilled from the bottom :/


Test for fit. MB screws not tightened down.


Finished MB section:

I initially looked at using 80/20 for the case but found it to be too expensive. Consisting of 1" square extrusions I also think 80/20 takes up too much valuable space on the interior of the case. Trying to fit 7 GPUs in the width of 442mm is going to be hard enough without also loosing 2" for the side walls.

The way it is now I have 442mm of space for GPUs. 4mm for the aluminum sides (2mm each side) and then another 2mm for the side panels (if I decide to use them) for a total of 448mm. Looking at how it turned out I think I could of increased the interior to 444mm and put the sides on within the space between the long aluminum pieces.

This is a learning process for me so I'm finding what works along the way

I think these are the two size angle bars I am using:

http://www.homedepot.com/p/3-4-in-x-96-in-x-0-050-in-Aluminum-Thick-Angle-56930/100337439#.UfNGDCTn-M8

Larger pieces for the exterior frame. Smaller ones will be used for the interior GPU stand.

I initially wanted to make it 4U but after measuring I felt it was a bit cramped. I may enclose the case to build a wind tunnel type enclosure if the temperature on the cards are too high with the stock fans. The power supply's will be in the front half of the case so I also wanted to have some space for more air to flow in.

I can fit 8 5U cases in a 42U rack vs 10 4U cases. The power requirements to support 8 cases may already be higher than can be provided as the environment has strict watts per square foot restrictions. I currently have one 20amp PDU to power the rig and I know I can get at least 30amp PDUs when the time comes but don't know if I can get anything higher. By that point I may need to acquire more floor space to accommodate the watts. I will have a better idea how many amps/watts each rig will draw after I get the first one going.

Basically my thinking was that case space was not an issue and I wanted to error on the safe side. If/when I build a second one I will have more experience to see if a 4U case will work. I will also be purchasing a nice mider saw if I build anymore as cutting the aluminum with a hacksaw and then smoothing out the edges with a dremel took a lot of time and effort!

Try out http://dgc.xpool.net:8810/

Any blocks found are paid to you immediately. No having to wait for pool confirmations or pay a cash out fee. Very hard for the pool operator to cheat you out of your share. No fear of having coins stolen from the pool wallet as it never holds any.

It accurately tells you what your expected payout will be if a block is found.

Just wondering if this should be the recommended settings for Casinocoin?

I am not familiar with exactly how these settings work and am currently testing them out. My reject ratio was extremely low with the default 1-60-120 but my miner has extremely low latency to the pool so maybe that has an effect.

For those hanging on my every rivet I have 12 more done

Please post after this has been resolved. I stopped testing at the pool because I didn't like my cards going up and down in temp due to the disconnects.

CSC is Casinocoin not CNC.

  Thanks!

This is really turning into a labor of love. It doesn't help that I am a perfectionist when it comes to this type of stuff
Trying not to let that extra hole drive me nuts  

Slowly making progress.



This is what the GPU holder will look like. Going to fasten it down somehow. Perhaps with some kind of quick release clamps on either side. Measured that there is room for 23-24 slots. That will allow me to have a bit more than one slot of room between cards (7 is the goal).

That or he can just pay directly in fiat based on the work performed. In other words he can pay people to mine based on what the exchange would have been not actually do the transfer of funds for people.

Thank you. Turned off my testing since it kept having problems.

Testing...you may want to upgrade your AWS instance.

We discussed making this type of pool in IRC even before multipool starting doing it. The big thing multipool is missing is the auto exchange feature you have implemented. From a technical perspective good work! I suppose you can take it even further and go strait to fiat.

Good for miners looking for quick profits without a lot of the work. I don't think this is good for the individual coins being flash mined but if you don't have a vested interest in them I suppose that doesn't matter.

CoinCasino.cc would be a good start.

Hi minerapia,

You were not able to get any shares with your hash rate of around 40 Kh/s. For anything under 100 Kh/s you run the chance of not getting any shares and subsequently a payout. I have sent you 10 CSC for your effort.

I don't think you need the ":47950" unless the seed is running on a non-default port. Also specifying "rpcport=47970" shouldn't be needed unless you want to change it to something other than the default.

In the process of building a custom case for my mining rig. Thought others may find it interesting to see the progress.

It will be going into a 19" rack so the dimensions were made to fit.

Dimensions
Length     600mm
Width      446mm
Height     221mm (5U)


What I have built so far



Using rivets to hold the pieces together



Made one of the holes too close to the others so the rivet wouldn't fit :/
Luckily I had enough room to drill another hole. Lesson learned.



Will update my progress as I get further into it.

If anyone would like to setup their own P2Pool node for WDC I have posted the source code based on P2Pool release 13.1 on my GitHub:

https://github.com/CartmanSPC/p2pool

This version also reduces the PPLNS window from 24 hours to 3.

Important note:
If you are currently running alternate p2pool code you have to do a new install. Alternate P2Pool code is not compatible!

Added Casinocoin.

BTW, there have been NO payout problems with P2Pool.

Payments for mined blocks are sent to you immediately. Mined blocks mature in your own wallet rather than the server. No having to cash out or pay any cash out fee's. You do not need to be running the wallet. Just make sure you use a valid payment address as your username.
