The MintMiner Ethereum / ZCash Miner delivers the Ultimate, High-Quality, and High Efficient solution for Mining!  The MintMiner provides proper cooling and program management of the for ease of use not seen with many Altcoin Mining Rigs to date.  Ethereum dual Mining with Decred & Siacoin are also supported.

The MintMiner system stays cool in most environments where open frame miners may overheat and shutdown, although not generally recommended customer units have run in environments with over 90F ambient temperatures.  Open air rigs cannot control the direction of the exhaust heat and are not rack mountable.  We have solved this situation!

We are happy to help with projects of any size.  PM with any questions.

Ethereum / ZCash values do fluctuate like many similar currencies, but at their current value a ROI (return on investment) can be achieved in just a few months.  As ETH and ZEC can produce a return on investment many times over. This is not guaranteed and we have no control over the value of Ethereum / ZCash however, it is showing great promise as many major institutions are investing.  

The MintMiner has state of the art GPUs, CPUs, RAM and Motherboard so, the hardware maintains resale value in Crypto Mining World as well as Computer Gamers’ Arena.

Programming and Delivery:  Once we receive your order, we go to work manufacturing your MintMiner.  Once all components are installed we program each GPU for the optimum efficiency for that GPU and optimal integration with other specialized components. The MintMiner is fully tested before being shipped which is in about 7 days from the date of order.

Let me know of any questions or suggestions.  Thanks for your time in viewing my RIGs.

Great job! Be sure to post pics of the 7 GPU rig when you're done!

Ordering myself a chassis to play with as well, might end up converting everything to this type of enclosure.

Are those RX 470? and how much you're getting on zcash with the latest Claymore's?

Yes, they are RX 470 4gb.

ETH: 165MHs +/-10%
ETH: 1000Watts at the wall
ZEC: 400MHs +/-10%   Claymore's v4.0
ZEC: 775Watts at the wall

For those who has little experience in building rigs, have a high electricity price, want to start mining from the box - I strongly recommend to take this offer seriously (even if AriesIV10 added haha).

He is added $300-400 on top of components prices - which is super low margin for custom things nowadays.

You can ship it to datacenter with cheap electricity and enjoy.

p.s. I will try to build smth similar this weekend using the same 4U server case

what are your temps there? i see no additional fans, also state your ambient

The airflow is from the motherboard to the GPU direction.  I have now removed the door completely to allow for maximum airflow.  Runs about 60C for the GPUs and 34C for the CPU.  Ambient temp is 71F(21.6C). 

what box is that like they asked in the other post it looks nice if you don't want to share that i understand why.

It is a modified server box with modified parts from Lowes.  Not too difficult to build with a little ingenuity.

I Might give that a try for my next rig i like building for fun, i found your link for that case and what you did, nice and thanks.

yours should sell a lot better then that dishonest one from china,


Thanks top .

very nice and clean build, the price is also great, good job

i only see those two fan near the cpu, are those the only airflow you are talking about, or there are 2 hidden fan behind the gpu in the second picture?

There are 3 fans in the mid section and 2 small ones in the back (by the PSU/CPU)

How much for just the case with the case mods completed? (I have mobo,psu,gpu)  :o

I would have to look at $425.  I have also added a larger set of fans (3 in the middle) for increased airflow for the summer months.

 :o  ZEC: 400MHs +/-10%  Claymore's v4.0

Yes, on the one that is in the picture, I am getting a fluctuation from 405-421 ZEC right now.  I am not hashing the CPU.  It is a dual core and have hashed at about 3-5 ZEC on a setting of 1 so, I figured that I would not use the CPU.

That is quite good. It seems it is quite profitable to mine the ZEC more than the Ethereum at the moment.

Compared to ETH - The profit is higher and the electric cost is about 25% less, yes, this is very good. 

wouldnt some data centers with hot isle/cold isle setups have a problem with that rig as heated air  will go the wrong way?  or can it be mounted "backwards" in a rack.

if you tried it at some point, what was the result of normal front to back flow (gpu->mobo) for temps? mobo and cpu, or more likely, the PSU cooked?

anyway very clean and compact setup, probably the best ive seen.

I have considered the mounting and I am able to put the 4U rack mounts on the other side.  The PSU has very little heat. 

It is stackable and mountable as well.  I do have open rigs, but the hot air cannot be controlled or directed.  This one takes care of that.

I will be testing with 7 GPUs today.

Evaluating:

1. Ability to work
2. Heat issues
3. Fit
4. Performance.

definitely interested in pics of that..

can you put another fan in on the mobo side where the expansion card slot covers go? maybe fit a 92 or something in that space?

Basically GPU mining need a good ventilation if you want to increase it's life.. just my thought..

I have thought of adding a fan on the CPU side, although another thought that I had was to move the fans from the middle to the exit (GPU side).  This will pull the air rather than push though the GPUs.  The fans that I am adding are 135 CFM each.  When I hook them up to 4 prong power plug they run at 100%.  When I hook them up to the motherboard they run at specifications/needs of the motherboard.  The only problem is that IF I move them to the exit end, the wires are not long enough and therefore I will have to add an extension...more modifications...which I am trying to minimize modifications.  Just thoughts.

I will deffinitely post pics.  

John1010 is mentioning the importance of ventilation with the GPUs.  I agree.  Right now the GPUs are running at an average of 60C with their fan speed at about 40%.  I should be able to get this down as well.

Thanks for the inputs!

This is a really clean setup. Congratz OP!  ;D Will check to create something similar.

The main reason for the creating this RIG is being able to controlling the hot air output.  Getting it into my furnace or out the window depending if it is winter or summer respectively.

I have parts coming in the mail today to perform testing and evaluations.

MSI  Motherboard which  ?????

MSI Z97 Gaming 5 - this one has 7 PCIEs and can run 7 GPUs

I have the same case - and I really doubt that it can fit 7 GPUs

Anyways, to have 7 GPUs running ETH you need a VERY good PSU otherwise your efficiency will be low

All - don't forget that you can buy this set up from AriesIV10 !

It's not really hard to achieve, my 4 RX470 8GB do 265-270, if I add 2 more, I'm up to 400 as well. They are heavily undervolted too, so power figures are somewhere in the 400W, system included.

Really nice rig though @OP!

awesome rig, would buy case

where can i buy the chassis?

getting a few of my rigs into this case ... then I can ship them to my ISP to join my BTC farm.

+

how many of the chassis can i stack on a 19" rack?

I do not know how many you can stack in a 19" rack, but It does provide directional/controlled air flow.

Chassis seems to be 4U, if we are talking rack 19" 32U, then you can fit 8 (in theory).

A standard 19" rack is 42U, so you can put 10 of the into a cabinet.

I made something like these about a year ago:
http://imgur.com/a/5lrtG

I put some big mofo fans into the front mask to create a wind tunnel, but there are LOTS of little m3 holes in these premade server cases, so i made my own custom case:

http://imgur.com/a/HAzQN


with this pull setup you can manage heat easily, even with hot-cold aisle in datacenters.

ps: my main acc zombie007 got stolen at last btctalk hack :(

I could have used these pics a week ago!  haha  Thanks for the Pics!

You can cut holes in that flapping metal front mask to insert big mofo 1-2A fans to make a wind tunnel :D I had real big problems with little holes, so i made my own case from sheet metal, and powder coated it. They looks so pro :D

Very nice RIG zombie007!

Today I am getting in another gpu and will make this rig a 7 GPU RIG.

I will post Pics as soon as I do some testing. 

I am also going to do some testing with the USBs - Trying to add GPUs via USBs.  I use the usb risers and was wondering if I can use the USBs on the Motherboard to run another GPU. Anyone had any experience with this?

you mean from a standard usb port/header on the mobo to a pcie slot adapter? no go.

the usb cables in risers just carry the pcie signals from the slot to the adapter. they do not use the usb protocol; the usb cables just happen to have enough individual wires and bandwidth to work so are convenient to use.

you could try a pcie port multiplier but not sure how well you could fit that in there.

Thank you for the information.  Yes, that was part of my question "Can the standard USBs interface a GPU."  Answer, No, Thank you.  

Second part of the question.  Does anyone have experience with these devices:  

PCI-e Express 1X to 3 Port 1X Switch Multiplier HUB Riser Card +USB Cable 1PC

its working, but doesnt worth the effort and the money. i think only linux will user 7 cards, you will have problem winth windows. Its easyer to make 6 card rigs with win10 imho.

I have these on a test rig (MEGATRON): 7 x R7-370s, Win 10, ASrock H81 Pro BTC mobo, 8GB RAM, 120Gb SSD.... working like a charm. The card goes into the last slot and connects to GPU 6 and 7.

Its currently mining ZEC - fast and furious, with CZM v5, runs cool

https://i.imgur.com/rYdnNWJ.png

Would you think that this would lend the opportunity to have a 8+ GPU RIG?

Yes.... but after talking to many members.... anything beyond 8 cards need Linux OR Windows Advanced Server with several registry hacks and special drivers... gets complicated.

Also you need bigger PSU.

Someone in Ethereum forum did 8 cards on Ubuntu 14.04.

If you want multi multi GPU, search for this dude on Claymore Eth thread, who did I think 18 x GPUs on Linux and Claymore had to add feature to allow more than 12 GPUs. He used a PCI extension daughter board - usually used for deep learning machines -- but that is super expensive and not practical for mining

Thanks for the information!  I am going to stick with a 7 GPU setup for this RIG.  There is only so much space in this RIG! 

What if use 7 such multiplerlers with 3 cards in each to build 21-card rig on a single motherboard? What if install 3 multiplers in each multipler resulting in 63 card per rig? Where significant performance drop will appear?

Look at the posting by citronick.  Looks like there are other issues that come into play.

It has been done actually by Nippy -- see this link and see the motherboard (its a USD$2000 PCI extension board for deep learning systems, like Facebook's Project Big Sur)

Its not as straight forward as ... just putting these multiplexors into an array ... you need Linux and special AMD drivers to make this work.... its entirely different animal all together. Claymore even needed to put a new version of ETH miner to support that many cards.

WHooooaaaah!  That is a BEAST!  Cool!  not profitable, but Cool!

working fine for me on asrock H97 Anniversary and 7 rx 480 cards (win 10/64bit) , i was not able to get the 8th rx480 working in that setup.
it also working fine for me in a GA-X99M-Gaming 5 (rev. 1.0) mobo and 6 cards ( the mobo have 4 slots : 2 x PCI Express x16 slots, running at x16 (PCIE_1/PCIE_2) , 1 x PCI Express x16 slot, running at x8 (PCIE_3) , 1 x PCI Express x1 slot ) .

has anyone tested this PCI-e Express 1X to 3 Port multiplier ?
I have 3x GPU mining rigs and managing them is a pain in the ass, if I could cut in half the amount of PCs that would be great.
Also I have 6x GPU rigs on windows 10, what is the max GPU supported in windows 10 ?

That case is pretty deep, any idea if it would fit in something like this?

Have you tried to go more than 7 gpus on 1 motherboard? 

Great RIG.

yes, but 8xRx 480 gpu rig not started with 7x 480 works fine, but 8x Rx 480 not boot

about 1050 H/s with clay 7.0 for 7xRx 480 Nitro

I think Big Sur is part of the Open Compute Project so it's OpenSource. Now we need only some small manufacturer (maybe local) who will want to build it  for less money :)

Actually big sur while it does have an expansion board it only uses 8 gpus, although it can run k80s which would then need changes similar to the OSS board, it would still not need much in the way of bios mods to work, rather a small hypervisor kernel change. The stock linux kernel is not happy with OSS boards iirc, and they do have a hard limit of 16 cards(just in the way of how graphics cards are allocated space today). If you want to see an example bios for a system that was made to work with 8+ cards on an amd mobo you should look up fastra II :)

I can ship worldwide and will can issue an invoice. Not a problem.

Aries are you willing to just sell the 4u cases?

I can sell you the case:

with no modifications for $150
with modifications for $250 plus shipping
Fans are extra at $20 each x 3 = $60

You should put these custom cases and full rigs on Amazon.com :)

What are the mods with the $250 case compared to the $150 case?

It looks like this case with the front and back swapped and the drive bay taken out to accommodate GPUs.

https://www.amazon.com/Rosewill-Server-Chassis-Rackmount-Metal/dp/B0091IZ1ZG?th=1&psc=1

@Aries,

I think you mean the $250 case is modified to fit 6 or 7 GPUs whereas the $150 case will not.
Correct?

And on Ebay. You guys just go and type smth like "GPU frame rig" and check Sold

I'm pretty sure that  AriesIV10's things will be selling well.

I have a store (also a Power Seller, TopRate Plus) - so I'm paying 10% to Ebay and PP for transactions, dont remember how many percents they charged if you have a regular account

EXACTLY - Well said.

Either one will hold 6-7 gpu's.  The $150 case will not have the modified brackets.

Check out our website for full modifications:  www.MintMining.com (http://www.MintMining.com)

Good job Aries, wish you the best of luck in your venture!

Hello,

I'm trying to built 7x GPU rig with MSI Z97 Gaming 5 motherboard. The problem I faced is that MB is not starting when 2+ GPUs are connected via USB risers. It works only with onboard graphic controller or with only one GPU connected to 16xPCI-E via powered USB riser. Please share what tweaks you make to get 7GPUs work

Any help is appreciated

Best regards,
Serge

I have 6 rigs with MSI Z97 Gaming 5 motherboard. All works with 7 AMD cards without any tweaks (plus M.2 SSD). It looks like you have defective motherboard.

Maybe the operating system.

Make sure you use crimson versions 16.10.1 or 16.10.2

Hi, nice to meet you I'm edoardo, I live in Switzerland and I starting new project for mining ethereum!
I need the case you use for your rig!

Do you have an email or another system for communication?

Thx and sorry for my English.
Edoardo
