proccessor is too weak, ram can probaby be sweapped out but an i3 or higer is best for rigs now due to algos like mtp

The processor does not matter as the GPUS are the main reason for this rig, you could probably still mine on the CPU, one extra hash is one extra hash, right?

It only has to do one job, is not a media centre or gaming PC... Nice looking unit anyway, looks well made too. Would be good if there were a choice of PSUs if you did not want to utilize or need all that power.

Complete rubbish !
Dependant on what coin you mine, the cpu and ram can have a massive effect on gpu performance. You must only mine a limit range of coins.
Several coins i mine require 4gb ram per 1080ti, and at least 1 dedicated thread per card, otherwise hash rate can half, or sometimes you cannot even utilise all cards.
I have been using a min of quad core (8 threads) and 8Gb ram in all my rigs for over a year now, and it makes a difference (to some coins)

At least the product looks interesting.
What is the dimension between PCI-e slots? Is it compatible with 3-slots GPUs?

At the risk of having this judged as being a thread hijack (I'm still going ahead with it Grin

), I was wondering what the best (i.e. cheapest) case would be for an Onda D1800 with 6 GPUs on it... It would need to fit the PSU as well I reckon. Don't want to splash out too much cash, but I'm thinking of moving this open-air rig to another place so I need it properly secured.

If cheap is really what you're looking for, just go for a cheapo Rosewill or some knock-off brands on Amazon or Newegg.com. No need to bother about long-term sustainability.

u sound like a bitnand shiller Cheesy

sorry for OT but this pricing is not sustainable in the mining space. a lot of standard solutions work fine. ok the dimensions is a really special thing about it but 90% of mining farms dont really care about it. shelf-space is not the limit, its mostly the power capacity...

Actually if you look at the dimensions of the rig, it is a standard 4U size. A lot of imitation rigs out there, including the Octominer, are non-standard size. The Bitnand rig fits inside a 4U rack case.

You didn't read what Marvell2 wrote. Yes, this CPU is too weak for algos like mtp (and its very likely soon-to-come offsprings).

The box does look good indeed, but nowadays if you want something future proof, you'll need to get more than a Celery and at least 8GB of ram.

The memory is upgradable, so making this rig future proof is not a problem. I would say the only potential limiting factor is the PSU, but then again that can also be swapped out.

Does Bitnand offer international shipping? I like this 4U case.

Hey!
OCTOMINER here. We have 4U cases in stock also and we offer international shipping.
We also have a new 12 GPU rig that has a 1151 socketed CPU, it can take up to 6 core i7 CPUs. Usually people spec it with a G3930.
We actually manufacture our own hardware to improve the reliability and functionality. For example our OCTOMINER VENTUS fans in our cases are even more efficient than Delta fans. We put extra effort in to get the fans as efficient as possible, the use double thick PCB boards, thicker copper coiling and imported IC chips and Japanese NMB double ball bearings. This helps bring the power draw down lower per rig and will also improve the lifespan of the fans.

I think Octominer is a scammy company. I've heard terrible things about them in the past from my friends. The quality of their product is also questionable... last I heard it's made by some tier-4 manufacturer. I would not suggest getting Octominer products. Angry

if your case wont fit in a standard 19" server rack and wont even accept rails, advertising under the 4U scheme is meaningless. the only people who care about "U"s are people wanting to put stuff in a standard rack.

That said...

I did a quick search and could not find any information about that 12-GPU board that would accept an i7. not on your website, and not anywhere else.

can you post links to the full specs?
what chipset?
how many PCIe lanes per slot?
will they run PCIe gen 3.0 in all slots?

Good 8-Gpu mining design, add knowledge to building my rig someday, I think 1500 watts is enough.

Off course, you can read on they official website, FAQ menu.

If the external width is 485mm, measuring on screen, that means c-c for the cards of about 42mm, 2.1 times normal PCI-PCI distance.
If you have fanless miner card where the cooler flange fills the gap to the next card (and fin direction is designed for that type of airflow), fine, but dual fan GPUs does not even fit (or it's fans will only suck the backplate of its neighbor).

With 60mm c-c you could place dual fan 8GPU on risers in a deep 19" case (mobo and PSU needs to be placed in front of the GPUS and careful design of the airflow is needed). There were some designed like this mentioned before.

Redesigned my now only open air rig to have 80mm c-c and turned off the circulating fan in the basement, now up to 57C but it's very silent now. Living near a server case, not that appealing...

I bought a bunch of cheap 4U old server chassis cases last summer that I am still playing around with. Basically its the same dimensions as this.

The most GPUs I could fit without them being too close and with a regular sized PSU is 6 GPUs. I wouldn't be able to do 8 GPUs like the above unless I got a slimmer or an external PSU.

So this seems like a nice setup and well designed.

Having tabs and mounting points doesn’t automatically mean it’s the right width.

None of it matters if rails aren’t available for it. Are they?
