Of course parallel and not serial. The available distributor I have leads from 1/4" to 3x10mm. Although the distance between the three exits is only some millimeters, I'm not sure if this will affect the flow to the third massively. It will take a bit of experimenting.

Just because something is widely accepted does not make it a fact.  Just because society says something is good and OK does not make it moral.  The huge problem is that most of the world just blindly trusts what is told to them or even taught to them in textbooks or go along with the popular beliefs.  We need to think for ourselves.  Why are you so frustrated about what I believe anyways?  I would think you should rejoice in freedom of choice?  If I agreed with you wouldn't you be stifling my freedom?  You obviously cherish choices in lifestyle don't you?  

Edit:  And as for your signature (Voltaire's quote)  "It is dangerous to be right in matters where established men are wrong" I could not agree more wholeheartedly!  There will come a day when I will be persecuted and maybe even killed for just saying that I believe in Jesus.  That is all it will take.  Just believing in Jesus will be a very dangerous thing because "established men" will disagree and say that I am wrong and say that my belief is a danger to society (even though as a Christian my hearts desire is to have a world filled with God's Spirit which is evident by the fruit of His Spirit: love, joy, peace, patience, kindness, gentleness and self-control. So I am not sure what the danger is besides the common belief that Christians are keeping the world from their "freedoms" which consists of sexual immorality, lusts, other sins and hate of God's word.)  If it gets to the point where Christians are persecuted (more than we already are) who will be right and who will be wrong?

Edit 2:  If this comes across as judgmental, I am sorry.  I just want people to seek more than what they have been told.  My heart is for people to see that they are so much more valuable than something that "evolved" from nothing.  They are created in God's image.  He loves us intensely and so deeply and the thought that we are not special and created by God is a lie that is being taught as "fact" today.  This is a truth that has to be revealed by God's Spirit though, so I will pray that anyone reading this will feel God's Spirit and see the truth for what it is.

Well, I believe that with 99% probability that should not create any problems, but if they all give 4.4, I see no reason to upgrade.

I believe Dell will have much bitcoin revenue. Don't forget about the 10% discount using bitcoin....

Listen, if you buy a miner today you may get a few coins out of it. Why don't you spend less money and just buy some bitcoins outright.

$26 for a plug pack, from China?

Maybe if it was from a top quality company, but lets face it, the rule of buying anything with a power supply from China is to bin it to avoid the explosion/fire.

Just annoys me that they did away with the USB Dongle design, asking buyers to take a punt on something costing £15-20 is easier than £80 (bare minimum) when you consider there are a ton of S1's kicking around on eBay going for less, no need for a pc, and with simple editing of a file, will give more gh/s for around the same amount of power usage (possibly).

Bring back the U1/2 form factor, and you'll have a deal.

Heh, we have a company we contract for that has a couple Techniwell TW700s sitting idle. I wonder how many one of those could run?

I agree. However, I still have a lot of old stuff here in my basement, so I'll only have to buy some fittings and new tubes. Especially with a 9-fan-radiator and a 1800l/h-pump, I guess it should be possible. In the worst case, one miner will be super-cool while the middle will be warm and the third one overheated...

you guys are weird, the concept is painfully simple.

you buy a TH - based on the current difficulty and assuming ideal (zero) variance, your daily payout is very easy to calculate. Thats what the site pays you.

If a machine in their farm goes down, they fix it and it has zero impact on your income. If a breaker trips and the farm runs at 80% capacity for several hours - you still receive 100% fixed income for the current difficulty.

of course, you could rely on a cloudmining where you 'own' a specific device and any error rates or downtime experienced by the machine or its pool directly decrease your income from the cloudmining.

your choice

Aww, that sucks. Will it cost the same if u order 2?

Why would they fake a whole data center for it.... in the picture it looks like they are well plugged and running..

Does anyone know who runs Bitcoinrigs.org? A brief search here shows that they resell AM and Bitmain gear but are also listed as a possible scam.
I got a shipment notification email from them (through stamps.com) that something was coming my way. I didn't open it, but eventually sandboxed it in a VM and looked at it, which surprisingly had my shipping address and the USPS tracking number is valid and shows something moving in their system.

I've never heard of these guys before, so I'm a little curious as to
a. Who are these people?
b. Where did they get my address?
c. What the hell are they sending me?

Thanks everyone. Looks like this is it:

Now I understand what Bitcoins are and that they are not recognised as any form of legal tender (even though Bitcoin mining is legal). However, there is no escaping the fact that you are essentially selling a currency business and are thus selling currency and aside from the faintly immoral aspect of this listing, the item is simply inappropriate for AVF to allow to stand.

I never said the full series solution is the best, just that people were overstating the amount of flow you need to keep the coolant at acceptable temperatures. 2l/min isn't much.

Having a large series string with a couple pumps does have other benefits as well in terms of reliability if there's a pump failure, and possibly easier routing of tubing.
