Custom Rackmount Shelves for Antminer Models

Excited to show off our custom rackmount shelves for Antminer models S9, S9j, S9i, S9K, and S9SE. These 7U/8U shelves can hold up to 3 Antminer bitcoin miners along with bitmain AW3++ power supplies. It's a perfect fit for traditional datacenter setups, helping with hot and cold air management. Right now, we have a clearance sale on the stock we have! Once these are sold out, we’ll only be selling in larger quantities of 50+. So grab them while they're still available! If you want to place an order, check out our site here: 7U shelf for S9,S9j,S9i 7U shelf for S9K,S9SE These shelves are also compatible with other bitmain miners like L3, D3, and similar units like dragonmint T1s.

Nice looking package, >35 some-odd TH/s per shelf with s9's, what's not to like? Except the prices... Ouch! Pretty sure I could have Bud Industries or other enclosure maker do a run for quite a bit less... Edit: looking again at prices, you show $3,600.00–$5,600.00, I now take it that is pricing for bulk quan and not each?

The bottommost picture, with 20 racks in the perspective view, reminds me of strikingly similar interior photographs from some bankrupt datacenter facility financed with securities fraud. The pictures I've seen were much less uniform with the contents of their racks, meaning that racks were filled with a variety of equipment, but only 1/3 to 1/2 of the each rack was filled. I also remember that yellow circle with the pipe pointing down in the far view. Is this type of the arrangement some industry standard for the datacenter equipment? I can't recall the company name. Maybe someone here saw it too and could refresh my memory?

FWIW Google Images only came up with that one. The yellow thing looks like a retractable power cord with an outlet box on the end of it. Nice touch vs having plugs here and there in that aisle.

We engineered the shelves ourselves for this deployment.  The last picture is one of eight cold aisle rows that will be loaded with S9s by the time we're done.  I get this is bitcointalk and scammers are rampant but we've been selling GPU cases for going on 3 years now and i wanted to offer these more out of courtesy to the community.  Yes, they are a little price but they're made in the USA, are powder coated, and function extremely well. These should also work for Bitmain's next generation of miners as well since they are pretty set on their form factor now. And lets be honest, the price of the shelf breaks down to 2.5% of the investment of the miners (not including power supplies...) Besides, who wouldn't want to put 21 S9s in a rack!?!?!

Fantastic , any way to do bulk order , but change out PSU spaces ?

Thanks for your help. Yeah, money laundering through terribly overpriced network installations is still the thing. It used to be done mostly by reshipping unused obsolete (or nearly obsolete) Cisco equipment with the original price at the time of the technology introduction. At the low end of price spectrum I remember Cisco color-coded Cat5 (not Cat5e) 1 meter patch cables for approximately $25 each. Nowadays Cisco is actively fighting those dodgy resellers. They are now transitioning do doing dodgy billing on digital audio-video installations. Some of those examples ultra-neat cabling jobs shown in magazines are in fact not computing installations but A/V installations serving digitized movies locally for residences or production facilities. I wish I had better memory for people names and faces. But the sales commissions for the people with right connections are awesome, e.g. from 50% to 75% or even 90%. I'm not trying to begrudge you of your markup. You are free to charge what the market bears. I also understand what were the NRE costs for the ASIC versus NRE effort for your cases. The ultra-neat-freak segment of the custom hardware installation market is such an obvious place for various frauds. Maybe the manufacturers aren't the most interesting, probably the buyers and the salespeople are. Just don't be surprised if some investigative journalist shows up near your production facility.

I do not want to give an address and name and contact info.  Just to find out shipping a set of 24 to 07731. you want 3600 for a 24 pack   that is 150 each plus shipping and a 90 day lead time. So you get to hold my paypal beyond the safe time to put in a claim for no delivery. I will pass. A 3 to 4 week lead time makes a lot more sense. But the gear is really good looking I will give you that.

Its not just Paypal security that's wrong here. Think of MTTR, Mean Time To Repair/Replace in case of any equipment failure. How many screws need to be untied/tied? Is it possible to replace just a single unit without taking offline the whole shelf? It seriously like anti-engineering as far as cost of operations.

Ok, so I have bad memory for names and faces, but reasonably good one for acronyms. Check out "NEBS Level 3". I'm going to give just a Wikipedia link for starters: https://en.wikipedia.org/wiki/Network_Equipment-Building_System . Please read that and if interested follow the links. You'll find plenty of examples of no-bullshit ways to rack up electronic equipment meant to be operated continuously. I understand that Bitcoin mine is not the same as telecommunication central office. Anyone reasonably intelligent would be able to decide for themselves which of the telco requirements don't apply to coin mine.

If you are serious i can get a shipping quote from the manufacturer, but i would assume ~$300 to NJ. Lead time is 4-5 weeks, not sure where you got the 3 months from?  I am not holding any stock so, manufacturer takes 1 weeks for material delivery, 1 week for forming, 1 week for powder coating, 1 week for delivery.  I like to add an extra week on to the estimate just to be safe.

Yes, they are manufactured in bulk and i don't have the time right now to offer them as single units (im still setting up 3mw worth of S9s).  They will come palletized from the manufacturer.  broken down the prices are $140-$150 each. I just dropped a line to my rep at bitmain, if they're willing to list them through their site for us i'll put the time into setting up a packaging / shipping solution and put some staff on it.  Until then its bulk or bust

OP might want to revise the title of this thread. I assume "Self" should actually be "Shelf"?

LMAO  - you have obviously never managed a large scale mining operation, this mine when fully upgraded will house several thousand S9's.  Now, to put that in perspective, the heat load and CFM requirements are massive.  I can stick a bunch of S9's on a shelf, but the blow back from the hot isle due to positive pressure is a nightmare.   Remember, every open penetration that does not flow through equipment means additional strain on the CFM capacity from your system.  It also represents a loss of temperature delta between the cold isle and hot isle.  Having lets say, several cubic inches of open space does not seem like much until you multiple that by a thousand.  You are now talking about just having 10 cabs completely open wasting conditioned cold air to hot air. In addition, the S9's do not screw in to the shelf, they sit on it. The only thing screwed in is the PSU so you can easily reboot the system from the cold isle...  95% of the time its not the PSU we have an issue with.  We have ~ a 70 degree cold isle supply with a 100+ hot isle exhaust and a 30 degree delta.  If you aren't an engineer, and have never worked in a pressurized / or data-center environment you have no idea what you are talking about, this isn't over engineering, its engineering to actually make the system work.

just noticed this, do you want any PSU spaces at all?  We used bitmain PSU's, mostly because we already have a ton of them and the way they draw air from the cold isle is idea.  If your looking for just a shelf to hold the S9 and not the PSU, we could easily do this, it would probably drop the price significant.  Maybe just have a bit of a shelf above to support a standard PSU or a standard server PSU?  You should PM me exactly what you're thinking, its not that hard to modify.

Very nice looking setup - I've seen your GPU miner setups, and I have to say you guys do nice clean builds.  My only issue with this one (and your GPU one as well) is on the power side, but simply because I don't use the Bitmain PSU's and my GPU rigs don't use consumer PSU's - I pretty much just use DSP-2000BB's.  Of course, you have to design to something, and there are so many different PSU's, I really can't fault you for your choice.  Your prices seem reasonable as well - having built my own large scale rigs for both Bitmain and GPU's, I can say that your price point isn't that far off from just raw costs of what my builds are typically running (primarily built with 8020 and acrylic). If anyone is serious about getting some and wants someone just to roll by and check things out, I'd be happy to assuming Greymatter is open to it, since I'm also located in Phoenix (which is what their website lists as their location).

Id be willing to organize a group buy if I get some interest from the community I have the ability to revive palet deliveries as work and break down and re ship individual units I wouldn't know shipping costs until I had them in hand but I would do it to help get these in the hands of fellow community members interested in small quantity units.

Those are nice.  Some one let me know about the group buy.

I would love 1 or two of these but I am in the UK and by the time I have had them delivered here it we are talking about 200$ delivery costs, I would ask for a copy of the plans so I could ask about in the UK about having some made up for me but I am sure I would be pissing in the wind. Kind regards Alex

You are 100% correct saying that I've never managed a coin mining operation. I have completely different background. In particular I'm not a mechanical engineer, but I have worked with them. I also don't normally do "operations," but in my company there's a team that specializes in acquiring bankrupt data processing operations, so I've seen quite a few and helped restart them under new management. I didn't made myself clear in my previous posts. I don't consider your design over-engineering, it is something akin to mis-engineering or show-off-engineering. It is for designed for "lookists" and quick sales, not for the cost-effective operations. From the mechanical point of view, you've only partially addressed the air flow and the MTTR issue. Your design seems to put the whole weight of the power supplies on the edge of the sheet metal. The better design would be to place the weight of the inside devices on a sort of ledge that is at least 1cm wide and lined with soft rubber. (Sorry, I'm not an ME, I lack proper vocabulary.) Basically your design seriously ignores the vibration and resonances caused by the high speed air flow. The resonances are particularly important when nearly the whole facility will be filled out with exactly identical equipment. Your design also wastes a lot of sheet metal for the bottom of the case (and maybe sides). The Bitmain miners are already quite similar to the Helmholtz resonator (https://en.wikipedia.org/wiki/Helmholtz_resonance). The multi-mega-watts facility will be like a mad-scientist punk-rock one-note-organ or maybe one-note-straight-flute ensamble. People already are complaining that they are loud, the vibration of the whole facility will badly affect it mechanically. The other MTTR issue is with the facility shown in the photo. The very long aisles, over 20 racks long, may look impressive on the photo. They are very detrimental to proper operations: it requires multi-person crews for maintenance. If people working alone are forced to work in it they will either skip important work steps or will spend more time walking around than productively working. I've seen what an experienced water-damage contractor could improvise in hours to direct dry-air flow around the equipment to baffle and cool it. The corrugated cardboard + plastic foam + particle board can direct the air around metal warehouse shelving no worse than dedicated metal racks and cases. It doesn't look good, but operates well, is much cheaper and has no lead time for ordering. I wouldn't advocate that for permanent facility, but what is going to be the expected operational lifetime of the particular models of coin miners?
