Just my 2 cents:

As hard as I try, because I would really like to have some shiny spankin' new SP30s (do they come in matt black with satin chrome bezels ?)  , I can not find numbers that produce a profit significantly large enough to offset the risk, without making unreasonable and unlikely assumptions about one or more of a) the price of bitcoin in the future or b) limits on the rate of increase of difficulty. Even best case likely scenarios indicate barely making ROI after assuming a very large risk.

This is assuming April RoadStress SP30 bulk buy prices, the 'KNC' discount, and discounting any delivery risk (however slight).

Perhaps someone else can plug some numbers into https://bitcoinwisdom.com/bitcoin/calculator that work, publish them here, and then justify their assumptions ?

Having said that, the fantasy of turning the basement into a server room (however impracticable the provision of power and cooling would be), the additional lure of the 'spread the hash' bait, and the David against Goliath (erm ... KNC) fable injects the kind of hallucinations straight into the temporal lobe that make me think, if only for the duration of a flashback, that if only I'd send ST all my money now I'd get to join the good guys in their eternal struggle against evil …

Nice hobby but unlikely to make much if any BTC …

We're waiting for samples from https://openrigs.com/
They are in the process of finalising specs on a product that is geared towards rack-mountable ASIC miners.
We'll post pictures when we'll get the samples.

I've been waiting for a long time for a professionally designed Bitcoin miner that plays nicely with racks. In every way, racks are the best way of housing multiple computers. You can stack them safely, screw them down, they aren't going to fall off the stack. You can take one out of the middle of the stack without affecting the others.

You can even buy a rack for home. Check out Acousti Products as an example, they even have rack cabinets with wood finish to make them look more attractive. I operate all my miners in a 24U rack cabinet from Acousti Products. It cuts out the noise, and all the heat can be taken outside by use of a Heat Ducting Kit - you just have to be willing to drill a 150mm hole through your wall.  The Active cabinets can handle a thermal load capacity of up to 7.2 kW, which is pretty good considering that you still need power for the rest of your house.  If you're drawing more than that, then you're not really a home miner any more... either that or you have put in more circuits and converted your basement to a server room.  

Having a rack cabinet at home may be a bit extreme, but it's just another option.  I like it better than having my miners stacked on my desk, being noisy and heating up my room.  Also, the rack cabinet is secure (lock and key).  Of course the other way to go, as mentioned previously, is to rent rack space in a Data Centre.

And the cost of such a large expansive facility to supply all that power. Datacenters aint cheap.

And UPS, backup generator, physical security, 24 X 7 maintenance, ...

Depends on your location! In my country, power costs are high (about $0.38/kwh) and don't forget the cooling!

You can hoard as many as you want for the same price. Doesn't that count?

.18 is not to bad. The summer rate is about to kick in here and it is .15 now you add in cooling and the fact hat it is quiter. That is an acceptable rate. At least to me. 

At 1.25 kw that comes out to $.18/kwh. That's still quite costly.

The list of reviewers was arranged by SyRenity few weeks before our launch.
ShadesOfMarble was the last one in the list and he got April batch.
The "Sample Unit" are ordinary units picked from the assembly line after testing.
We did the same with all the reviewers. We asked for a fair and true review only. Uncensored.

I'll second that, my SP10 was packaged immaculately - it doesn't take much to make sure a mining rig is safe during shipping... some simple corrugated cardboard cut in the right way, is simple, cheap and effective. 10/10

The post I like most about our packaging: https://bitcointalk.org/index.php?topic=521520.msg6097517;topicseen#msg6097517

Let's have a look at the "competition", the first frankenjup arrived in bad condition:

I had expected KNC to do a better job!

I guess it depends on whether you cram them into such a tight space that they compound the temperature before it can be exhausted.

I'll just have to wait till someone comes out with devices based on the Spondoolies chips that fits more into my mindset

That and continue to look fruitlessly for EU rackspace thats reasonably priced, maybe I should build my own

Noise i can understand, but heat? Isn't heat the same? If you have 5 devices that need 200W aren't they the same with 1 devices that needs 1000W when you measure the heat output?

Thank you, I will take this into account. Have they priced the hosting of the SP30 yet?

For bulk SP10 customers, we can do an intro with the owner of a WA DC with the following costs:
160$ / SP10 / month (minimum 6 months, one month deposit) + one time 100$ setup fess (includes the cables and mounting ears)

You know, I've been looking into this and have hit the inevitable roadblock of power consumption vs. space...

I found a "high power density" data center in the Northeast US. They are familiar with BTC and would love to have me as a customer.

They rent bulk space by the cabinet, standard 42U.

At 1.5U I could stuff 28 SP10's in a single cabinet.

Unfortunately, even at this "high power density" datacenter, they max out at 18kw per cabinet.

That allows for 13 SP10's or 19.5U, leaving 22.5U of empty, unusable space in the cabinet.

The only way I can see to feasibly "fill" a rack is with a purpose built submersion cooling system.

We simply don't have the bandwidth to do it. We'll gladly sell our ASICs to anyone interested in developing additionals form factors.
