Secondly, you seem to still be stuck on the "it's a scam!" bandwagon. Even the hardcore trolls in here have given up on that one.
No, they haven't. It's still vapourware until a single unit is delivered. Sorry, I should have clarified. The smart ones have. |

As bad as the Apple bastards. I mean hell, I've ordered one and I'm pretty sure something will be delivered, but I am seriously still trying to remain objective at least. |

If anyone with one or more paid units for the first batch wants to trade his pre-order position for a few bitcoins (10-15, negotiable), feel free to send me a PM |

People typically don't know which batch they're in 2. Allegedly, as soon as the first batch ships, the price for new orders will rise by $100, which is more than your offer 3. BFL would need to agree to the position trading, which is far from certain |

Wouldn't it be up to the buyer to decide where to ship it to? (ie. if I pay the original buyer then all that would change would be the shipping address, and of course some Bitcoins would change hands outside of BFL) I take it from your reply that you are not willing to trade your pre-order position for a few Bitcoins, are you? |

Not for this price. I ordered my first one 5 weeks ago, the other ones somewhat later, and ASSUMING that I'm in the first batch, which I have no evidence of, you can acquire it for $799 + $10 shipping via private buy-it-now auction on eBay, once I have received it. Edit: Actually my memory is not that great as to the precise time I ordered it, but I am positive that it was 4 to 6 weeks ago. |

LOL for putting a fan under that PCB and one on top. Does this forum have a facepalm button ? Guess I was wrong thinking they wouldnt be that stupid. Then again, maybe they arent, and the underside is actually getting hot enough to warrant a fan? |

Then again, maybe they arent, and the underside is actually getting hot enough to warrant a fan? Well, the current pictures clearly showing improvisation. Nobody would like to have an external fan under the box. They are under time pressure and can't fix this without changing the mechanical construction. For me it's quite clear that the two big logic chips, and also some other components, are getting so hot that they have temp. hotspots on the bottom of the PCB. And there is no airflow. Cooling a chip with a heat-sink and a fan from the top side is common, but when my chips are getting hot they transfer a lot of the heat to the PCB also. Often it's a good idea to have any kind of airflow also on the bottom side of the PCB. A good example are GPU cards. Have you ever touched the bottom side of the PCB at the place where the GPU's or Voltage regulator are placed under full load? Also other FPGA designs (e.g. Icarus) getting very hot below the chips, even with a heat-sink + fan on top of the chip. And the Spartan-6 is not such a large FPGA which consumes so much power. |

Then again, maybe they arent, and the underside is actually getting hot enough to warrant a fan? Well thermal energy has to go somewhere but if the bottom side of the board is getting hot enough to warrant a dedicated fan then that would indicated insufficient cooling of the heat sink. As the heat sink heats up thermal energy will flow to the coolest spot (i.e. the bottom of pcb). Even if one wanted to cool both sides of PCB a designed solution would be something like top

|F| heat sink

|N|--------------------
| | mining board
bottom
The fan blowing from the side with the board perpendicular to it so roughly 2/3rds to 3/4th of airflow is across the top of the board and the rest to the underside. |

I was under the impression that the Icarus only gets a little warm on the underside of the PCB, I remember somebody said it's like a warm mug of coffee and ngzhang posted that's a good way to see if the installed heatsink/fan is doing a proper job. Touch it under the PCB and if it's too hot to keep your finger there the heatsink/fan is not enough. I only have access to the ZTEX 1.15x with the Spartan 6 and it barely gets _warm_ (with the supplied Xilence northbridge cooler). But only one FPGA on the board with this design. |

I'm looking forward to youtube videos of these things actually running.
I'm curious if we can buy these in person. I wouldn't mind buying a round trip ticket to go pick it up and pay in person.

Ask them. If they say no - then either they are dedicated to those who have already paid them (unlikely  ) or they have none available to go out the door yet (likely) If they say yes - there you go  Edit: then let us all know. |

Didn't they plan to ship by the end of last week or something?

Well things aren't looking so good for that ship date. Especially considering their rep that was on these forums has disappeared.
I have a hunch that if they had good updates for us they would announce them.

Allow me to rephrase: I'm looking forward to people who ordered one / someone I trust getting one and validating it! And yes, they e-mailed me last Thursday saying the first shipment was going out soon. I expect someone should get a special package this week! |
