I decided to host my Jupiters at home as the power consumption turned out to be less than originally advertised + the miners are almost silent + free heating.
For home users check if your energy provider is the cheapest. I switched from British Gas to M&S Energy. Electricity cost with BGas was 13.6p for kWh, but only 11.02p with M&S.

KnC originally promised Jupiter at 250Gh/s for $7k.
Is that supposed to be an argument supporting the statement that "They will have already compensated you by delivering over TWICE the hashrate you paid for."?
They have never lied about their intention to deliver on time.
They might not have lied, but they definitely misleaded a lot of people. "All current paid orders will be shipped no later than October 15th." - This is a non-ambiguous statement. You know perfectly well how UK laws treat misleading information and for that matter any EU Law. If there is a court case and this piece of evidence is provided you can be sure it will be sufficient to conclude there is a delay. And last I would like to post my views on the Delay situation: First I want to state a very simple fact, which some people tend to miss: KNC is a for-profit company and there is no denying that. Their prime objective is to make money.
On the other side of the relationship are the KNC customers, who again are for-profit entities and are here to make money. I've seen people claiming the opposite on the forums saying "oh You should be happy to help Bitcoin grow and not care so much about ROI". I find it very hard to believe that there are people who will willingly pay thousands of USD just to help Bitcoin grow and prosper. Nobody is here only or mainly to support the Bitcoin network with money outside of his own pocket. Everyone is here to make a profit as their prime goal. Nobody is thinking: oh I will invest 7000USD in this company to help Bitcoin, regardless of ROI and just feel happy about myself.
Bottom line: ROI is everything for everyone.
To simplify things I will compare ROI to a set number of days: each day represents a portion of the expected ROI. Imagine it like a big apple pie, where one piece gets rotten and bad for each day that passes, so you have to throw it in the bin. So what happens is for every day that KNCMiner is late beyond the advertised shipping date a piece of the pie gets thrown away and eventually I will receive half a pie or worse. When does it end? How far beyond the advertised date KNC would have to be late, before they change their position and realize that customers are being injured financially?
Would customers feel good about KNC if they were to receive their miners 1st of week of November and all November orders were to follow from the 15th November? What about 10th November?
What time window do KNC find acceptable for delays to occur in? |

The main concern raised here today is the issue of compensation for delayed shipping. I take it you will pass this along to Sam and we can expect an update tomorrow, 14th October, agreeing to compensate 1.5BTC per day late (recalculated at next difficulty rise)? They will have already compensated you by delivering over TWICE the hashrate you paid for. Remember that it is much easier to BUY a magic money making machine than it is building one from scratch in 4 months and anybody pre-ordering ASIC miners should know there will be risks. There's no such thing as a guaranteed ROI and if you can't handle that then you should think about retiring from Bitcoin mining before you get an ulcer. Right now Bitcoin mining is like a horse race and all we can do is try to figure out which horse to bet on. Rest easy knowing that your horse is still doing pretty damn good so kick back and just let them finish the race. They are running as fast as they can. You failed all your math tests, didn't you? |

In line with the general feeling in the topic towards KNC*  *No hard feelings guys, just trying to lighten up the mood a little bit  |

I'm thinking of buying 2x 140mm fans and just put them with cables ties on the outside of the case at the rear (exhaust side), so they can help a little bit with removing the hot air. Thermalright TY 143 look nice and coupled with a fan controller you can run them quiet and slow or noisy and fast. L152 mm x H140 mm x W26.5 mm Fan Weight : 170g Fan Speed : 600 - 2500 rpm (PWM) Sound Level : 21 - 45 dB(A) Airflow : 31.4 - 130.0 CFM Or one can get a more advanced one with a display and thermal probes = monitor the temps inside the case directly  Hey Cyper, wouldn't it be better to add the souped-up, more powerful fans as the inlet fans and put the existing f14's at the rear to suck out the air? I think it would be more important for temperatures to improve the inflow than the outflow. That's another option. If I had a miner in my hands I can tell you which one is better as I can measure the temps with my IR thermometer. But I don't. I can even change the intake as well so they are all equal in performance - front and back. |

The pre-installed fans at the front of the case are intake fans?! Are you sure? That would be very poor design if true. I assumed they were exhaust fans. But yes, I think it's an excellent idea to install fans on both ends of the case in a push-pull configuration. Yes, intake. I think it is better that they are intake as there are no other fans to supply fresh air into the case. Adding a second set on the other end to exhaust will probably improve the airflow and the temps:  |

are most of the problems on Jupiters it seems?, if so, and caps are the problem, sounds like a controller board and/or power issue to me, but I'm not an engineer...lol
I would invest in a smoke alarm and put it next to the miner, so I know if it starts burning. Still can't save it, but at least I'll know. |

my connection home is adsl 8 mb is enough? or i need put fiber 30mb?
best pool advise?
anyone can helpme Mining doesn't need speed, so even with 1Mbit/s you would be OK. Try Bitminter or GigaVPS Private Pool. |

I think it should be safe, i personally use google drive as i use my google account for a lot of stuff.
I will use both (Dropbox and Google Drive) |

Anyone know what the cut-off date was for October deliveries?
I thought it was mid August but I see a mixture I think. (And was KNC accepting reservations before the payment date?)
I'm in a group buy here with order #4999 on a Jupiter and we all pretty much think an October delivery.
Thoughts appreciated,
IAS
Anyone? 1-2nd of September I believe. |

My wallet.dat is encrypted via the Bitcoin-QT and then put inside an an encrypted rar archive. Both passwords are 190 bits according to KeePass (30 characters long mixture).
Why is that not secure if I put it on Dropbox?
Because I know it's there now? No, you have some strength with that system. Even if someone got the wallet you have a long time to move the coins out of it. But I I will never find out if someone have a copy of my wallet.dat. |

How is it that I paid on June 4, and people who paid on june 8, are already receiving their orders?!?
Because you didn't wash your hand when you last used the toilet. |

Received my Jupiter today. One of the large fans in the back (not the heatsync fans) seems to just not work. Should I not be mining?
Connect it to a desktop pc if you have one and see if it work there. |

looks like 2 saturns may run faster than a single jupiter.... or am I dreaming?
Because of less heat, thus better performance? |

Are the 140mm fans pwm? If so, maybe they are not being told to run fast enough by cgminer? Could be a software fix.
Or maybe buy an external fan controller, so you can turn them up to whatever speed you like.
I was told over the phone that they run at 12V, which means max speed. Someone here also mentioned that they use 3 pin plug (12V, Ground, Sense), so definitely not PWM. |

I wasnt too pissed off about the delay, rather that when I ordered shipping was stated as September, after emailing KNC my orders have now changed to delivery by October 15th.
Can you point me to a source where it actually states that all orders will be shipped by September. I just opened an archive of the website from 22 August and it states Shipment begins in September. What did it say before that? |

If it were not for Bitcoinorama, I would have surely gone nutz by now being in the dark as they say... I for one vote that O'rama gets a Jupiter for the service he has provided us in behalf of KNC He has weathered the storm thru thick & thin
LOL, what service has he provided? Distracting us from the fact that shipping in September went to October. You can't have everything You got 550GH/s instead of 400GH/s I call that underpromise and overdeliver. If that was BFL they would have put 3 asic chips (410GH/s) in the Jupiter instead of 4 without any hesitation. |
