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.
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.
I've personally designed miner boxes from cooler boxes for the various ASICs I operate (L3+, etc.), and I've found they all work well as long as you have a way to ventilate the air the miners create, and you monitor temperatures as needed so you can add fans to increase intake or exhaust or up fan RPM so the miners don't overheat. I've seen people design miner boxes that twist around apparently to trap sound and to allow air to flow, but in reality those designs restrict airflow too much to be useful. Always make sure to test what you make over an extended period of time to ensure your design can work 24/7.
What are your thoughts on designing immersion cooling boxes ?
The 3M immersion cooling liquid is a major cost component. It's very expensive per liter.
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.
If you want to maximize your GPU's life, and hash rates of your cards, build an open air rack. My 8 GPU racks have at least 2 inches of spacing between the cards. in that case the cards are going to be right next to each other meaning each card is going to be sucking in the heat from the neighboring card. The result is once the system warms up. all your cards will be hitting max Temps, and hash rates will drop as the card try to keep temps under control. With something like that you would have to use blower style cards and they don't cool as well or hash as fast as traditional cards.
If you want to be serious about this. Build open air rigs, and keep them at floor level where the cooler air is.

Boy you are totally wrong. I have over 700 machines and at first I thought like you. Testing and research tells you the exact opposite. Forcing air through at a rapid rate with enclosed units will cool the card. I have both still but only like 40-50 open air left to convert. Temp on enclosed rigs are normally 10C cooler IF THE FANS ARE GOOD.
Also on the ground is incorrect, they need to be about 2 ft above ground for optimal cooling. The reason is at ground level the rotating air (vortex) is present. At a level higher that is eliminated.
This looks nice but I hope those fans are fast. Honestly I like Octominer solution best with fans on both entry and exit.
Agreed, the enclosed casing forces air to ram through the GPU. Surprisingly, enclosed case like this got much better cooling performance than open-air rigs.
Now, the 8-slot case looks like really sweet deal.
My rigs are 7 Vega cards with homemade case, and the costs are:
Motherboard: 150$
Ram: 8gb sodimm: 40$
SSD: 128gb mini sata: $50
Power supply 1200W, breakout board and 17x power cables: 100$
Wooden and aluminum parts for case: $20
total: 360$ + time effort to make the case.
So this nice looking case is just a little bit more than my DIY solution, having much bigger PSU but a little bit less ram and ssd. I wish there was such a deal when I was building the rigs, but now it doesn't make sense for me, only if i was going to build new rigs.

I think ram can be swapped out. Though tbh, if you're mining on Linux, 4GB ram is plenty enough. You don't need anything more than that.
Re: Very first tests P104-100: 39 Mh/s ETH; 470 sol/s ZEC - Nice GPU!
you can buy a 1080 for $300 used and you can get 40MH with the ETH pill.
why would you buy a $400 card, for the same performance, and less resale value? that P104-100 can only mine and doesn't have display outputs, a 1080 can do everything else, making it much more appealing to potential buyers.
hell even the 1080ti is a better buy, less than $500 and does over 50MH with the pill with very low power use.
keep crying about your poor investment, its ok.

..i was bought 2x P104-100 one for 277 (321$) and i have stable 40+MH/s on ethash i was really happy becouse my electricy is only 300W for both (and this is the reason - electricity)
POWER limit: 70
Core Clock: 100
Memory Clock: 845
cool story. my 1080tis use less power than that.
it's not very impressive. you could have bought a 1080 for less. they go for 300 all day used. sometimes even less
What you are saying makes no sense. How can you compare a new card price with old card price? The P104-100 is $400 brand new, that's a MUCH BETTER deal than buying some used old 1080 with unknown quality.
does a new card perform better than a used card? NOPE.
why buy a new card with a 90 day warranty, when you can buy a used card with 2+ years of transferable warranty left?
i've never bought a used video card that was damaged. its VERY hard to damage a video card from end user use. be it mining, or overclocking, or gaming, or whatever. the cards have built in protections from damage. if a card gets damaged, it was probably defective anyway and if you buy a used card from a manufacturer that carries a transferable warranty (like EVGA), if anything goes wrong you just RMA it no big deal.
again, no reason to buy a p104, unless you get them for like $100. then the risk of a failed card might be worth it.
It's about negative selection. People dump used graphics cards that are broken. You will encounter a high percentage of broken cards in 2nd hand market.

Re: Very first tests P104-100: 39 Mh/s ETH; 470 sol/s ZEC - Nice GPU!
After seeing the performance of RTX series, I am more convinced that the P104 is still the best mining card on the market.
40MH/s+ for around $4xx with the P104-100 is a really good deal imho. I don't think it's good to compare to AMD Radeon because per card hashrate AMD is much lower, and consumes much more power.

Agreed. P104 has surprisingly stood up to the test of time. The MH/$ and MH/Watt figure is still the best. I just wish Nvidia would release a new mining series card using the RTX series.
It would be sick to see a P-series card based on RTX 2070 pulling in 80MH/s
No.
1080s are cheaper. Get the same hashrate. And have resale value.
P104-100 is a terrible buy.
Ugh, not this shit again. You can go out and find second hand P104, and you'll see how WELL these cards have held-up in value. They are WAY more efficient than GTX 1080 for mining Ethereum. Furthermore, P104 is DEFINITELY cheaper than 1080.

Is it dangerous to connect multiple ASICs from one PSU?
it's the other way around. it is dangerous to connect multiple PSUs to a single ASIC. you can connect as many asics you want to a PSU as long as both your PSU and the 6pin connected can handle the power needed. from a theoretical point of view you can have 4 z9 minis connected to 1 APW 1600w psu ( each z9 mini takes about 350w if not overclocked" ). how ever i would not do that until i verify that the 6 pin connectors which are going to be split can actually handle the load.

You don't want to run your engine on max RPM to loong.
It's the same with PSU's.
this is completely based on your own or someone else's speculations and it has no solid proof what so ever, the max you see on the label is the safe point which a good psu should handle all day long. I have been pulling about 970w of a 1000w psus on my rigs for years and zero problems, it all comes down to the room ventilation and the quality of your PSU. bitmain psu is a solid psu. i have some A3 and S9s slightly over clocked consuming close to 1500 for ages and never a problem with the PSU. you can test it out yourself if you like.
Yep, agreed. I haven't had any problems with my Z9 running at max settings. Bitmain left lots of room for tuning in these things.
I just got a text message from UPS about import duties. I am in Texas, USA.
The are charging me 367.87 !!!!
This is the breakdown:
IMPORT CHARGES
NOTE: the total value used for calculation of all Duty-based fees is 0.00.
Government Charges: 356.87
Brokerage Charges: 11.00
Freight Charges: 0.00
356.87 / 1400 (2 Z9 minis at $600 each + shipping fees) = about 25%
Looks like US folks are getting hit with the new Trump tariffs on Chinese goods.
Ugh. Is anyone facing the same issue?

That doesn't make any sense. Trump tariffs target raw materials and semi-finished products. Z9 Mini is a fully-built Chinese miner, which should not get the 25% tariff.
Now that RTX 2080 series have hit the market go and just do a simple check on Ebay for the Rx Series, the 570/580 all cost less than 200 dollars and we can build a miner with 1000 dollars or even less if we can wait. That would be a 6 card miner which would give us 180 mhs stable compared to single RTX 2080 ti it is clear who is the winner here.
Not worth to use RTX 2080 series for mining when with that price of a RTX 2080 ti can build a big 6 cards miner now.

Yes and no. RTX 2080 series will likely see very strong resale value due to its freshness. I think you can sell your 2nd hand card at near MSRP if you get it first.
I think ultimately we need to see how good is the GDDR6 at overclocking. Afterall, it is new technology that is still largely unproven. If GDDR6 turns out to love being overclocked, then RTX 2080Ti will be a BEAST.
