Can't speak to the price, as we use exclusively Nvidia these days but I've used a bunch of these Chinese cases - they're all much better than open frame rigs IMO, as you can control airflow, and most are using riser-less motherboards, which is a must have for me.  If you're home mining, then open frame rigs are great - not saying you can't industrial mine with them, they just are much more work in my experience.

Some cases are better designed than others, and for my purposes their G12 isn't the best - in particular how they have airflow setup.  I suspect they didn't spend any time modeling airflow, and just tossed vents and fans all over it - by this I mean they have vents on the front that are far too close to the intakes, so if there is any kind of positive pressure inside the case, it's going to short-circuit the airflow and suck in hot air from the case.  Then it has two kind of random fans stuck on the back top, which makes these cases unstackable and I have no idea what they thought they were doing with them, as it disrupts the straight flow of air you want from the front right out the back.  Venting on the back is a bit more of a mixed bag depending on what they're doing - the open area around the connectors I personally like, because it tends to help the airflow around the PSU, which has a tendency to trap air around it and get hotter than normal.  I also like the extra-wide card slots, as once again it helps keep the air flowing inbetween the cards, instead of just over them, like the slots across the back top do.  All in all not the best design - solid meh from me.

My preferred cases are these:

Although I've used these with success as well, although I prefer the PSU on the other one as it's a more tradition ATX:

https://www.ebay.com/itm/8-GPU-Mining-Server-Case-w-4-FANS-Motherboard-Power-Memory-Rsiers-Frame-Rig-ETH/401486164608?epid=27014163342&hash=item5d7a70b280%3Ag%3AhaIAAOSwcSxacuOV&_sop=16&_pgn=3&_sacat=0&_nkw=gpu+mining+rig&_from=R40&rt=nc

Generally on these cases you'll see vents on the sides or top, but they are more to normalize pressure in case (to extend fan life) than for anything else - although they do disrupt airflow a bit.

Also keep in mind that any of these machines PSU really isn't going to work well at 110v - I'm not saying they WON'T work, just that they won't work for long.  

One more somewhat random comment - as I was searching on eBay for cases, I ran across this:

https://www.ebay.com/itm/MINING-RIG-GPU-SYSTEM-MP1061009N-9xGPUs-6GB-225MH-s-ETH/142870841634?hash=item2143c40922%3Ag%3AJzcAAOSw2khbTTpZ&_sop=16&_pgn=3&_sacat=0&_nkw=gpu+mining+rig&_from=R40&rt=nc

Before you get excited it's a scam, in particular the fact it says 'PLEASE NOTE: Delivery ~ 30 days', so just be careful - I've run into that lately on eBay, they try to get outside of the 30 days easy return period the eBay normally provides.  It never works, but it can tie up your money and be a huge PIA.  I also wouldn't buy from random places you find on Google - unless it's a provider that's been around for a while, just stick to eBay or the forum (with escrow), and you'll probably have a good experience.

Either way, Good luck!

I don't really think that it's the wisest thing to throw money at mining rigs anymore. You do make some profit but the initial investment recovery time is REALLY long. You could be better off buying some coins from the market instead and hope that the bought coins will moon.

Just my 2 cents.

[Ametros]

Ok, i got your message.
But i wanted to buy these..
Let's see what they are gonna tell me.
I am gonna ask them for further details through E-mail conversation

[Geraldo]

No argue about worth it or not for buying mining rigs nowadays.

To be honest, with all of that spec, $3000 is a reasonable price (if it right), you've reduced rig building time that will take a long enough time if you were do it yourself. On this bundled, each GPU cost you under $300 (not bad), but we don't know are those cards brand new or used card.

Let's see what they are gonna tell me.

Waiting for the result!

[leonix007]

Price wise is reasonable

and power consumption for 12 GPU + cpu system at 1600w is also a plus

however, risk is high, not sure how they treat warranties

I was just overthinking the way bitmain handles horrible warranty claims

I am not saying that they are right or Wrong but as you stated about specs, for $3000 and 6-7 months ROI that is way better than homemade or another custom mining rig
after 3-4 days of enquiry
and they told me that these cards are new and custom made for mining
I ordered Two G12

[Souran]

415Mh/s with 12x RX 580? with that power consumption, I highly doubt it

[leonix007]

415Mh/s with 12x RX 580? with that power consumption, I highly doubt it

yeah. unheard of RX580 doing 34+Mh/s working on a low powered rig

At least they could provide a working rig Video or images in action

[ikicha]

12 RX580 only for $3000? this is cheap.
New or secondhand?

RX series is best to mine Ethash and Cryptonight-Variant algorithm

I watched a video about 3 months ago and user stating 37MH/s+ on a Nitro card with 85-90W power draw

[leowonderful]

The fact that these cards are also 8GB variants is also pretty impressive, considering in the US the price for the cheapest 8GB 580s hovers at or above $250- the Aorus 8GB is $259 as I speak on Newegg, other cards lower during a deal. Note that they say the rig doesn't come with an OS, however (not a big deal to most).

I do find it a bit suspicious that the site only accepts BTC and I haven't found any information on the Domino miner company yet, searching using their website name Dominorig and also 'Domino miner'. Not calling it a scam yet though due to lack of info, but at least the miner specs seem somewhat realistic.

If you want to purchase the miner or take a look at Domino's other offerings, here is their site.

[Omg9500]

415Mh/s with 12x RX 580? with that power consumption, I highly doubt it

I have a 13 RX580 rig with 402 mh/s and 1750W draw on the wall. Hence power consumption is possible. But max hashrate to squeeze out of one RX580 maybe 32 mh/s x 12 = 384 mh/s.

Nope, Right now i didn't got any
But they did an Email about getting coupons on listing of next batch

Dear

We are team of professionals and we made custom factory changes in memory timing for particular mining usage in GPU, That is why it did not require any Overclocking nor any particular OS.
We used a Special BIOS for our custom motherboard also.
That's it we can not reveal more information.

Dear
We provide 180 Days of Warranty period after the Shipping day of particular product.
If anything  bad happens within warranty period we will replace the hardware part OR whole product if needed.
Please read our Terms & Conditions for warranty at Domino Technology.

Dear

When our Technical person Designed our models they did not just placed Two fans on the Upper side without any calculations.
We could cut those two upper fans if we wanted to make it more budget friendly but we also have to design a way for proper air flow in storage

which OS is installed and what mining software comes as default?

[swogerino]

Sounds fishy as 12 Gpu do not run well or do not run at all with only 4GB of Ram. There is the common consensus between small home miners that up to 8 cards can run with 4GB of Ram although not recommended, the usual recommended Ram is 8 GB if you are mining with a device which has more than 8 cards.

After searching the website of dominorig I don't see office location so anyone interested can go there and check by themself and also the website is done in a very cheap and unprofessional way with Wordpress. These are big red flags for me so I would be cautious to say the least.
