I'm talking about the sierra. Yes, the chip level heat to be dissipated will be lower, but there will be around 1000W of heat anyway in there. Having the units in a real datacenter will help a lot, but anyway, putting the radiators where they are makes no sense at all.
Another point? Instead of using 2 big radiators, as CT does, you use 3, one per chip. In other words, even if there was the space, you can't fit a 4th board in a sierra case.

I personally am planning on stripping my machines and putting them in cases of my own design. If I could get my order as parts a week earlier (by not shipping Canada and then back to the US)... that would be just fine with me.

Sure, even having the boards 1 day earlier would make it worth... Something tells me that it's not gonna happen, anyway.
HF, if you are listening, just ship me boards, do it a few days before (hell, you have them there, ready!) and we will be fine... I will have something to do under christmas.

I thought their prices were about the same (if you factor in fully triggered MPP -- which it most likely will be).

You are correct, but i still don't consider the MPP even an option until when they give us a deadline for its shipping. From what it's written in the "contract", it could be 2015.

Ice, please tell me the sense of putting the radiators in the front of the sierra case, so that the whole board has to endure the hot output air of the radiators. I feel bad for the PCBs thinking that they will be exposed to a 1500W heater.

This is the level of proper designed cases HF has to offer.

What 1500W? Honestly the location of the radiator doesn't matter that much. Think of an aircooled board (like KNC) the air on the downstream side of the board is going to be just as warm. Does that mean the downstream VRMs, and caps, and etc are going to be destroyed, hardly. The radiators are OEM versions of Corsairs HydroCool setups and lots of people put those radiators on the intake side of computer cases (because that is the only place it will fit on some cases) and they work just fine. Corsair even recommends that as an acceptable mounting location.

The air will be warmer (maybe 5C warmer) but it isn't like the air on intake side of radiator is ice cold and the exhaust side is hot enough to melt plastic.

That being said Cointerra's rig looks very nice. Only thing I would change would be three fans across the front and ducting air from the front to the PSU so it doesn't need to breath from the side (which in a datacenter rack is going to be non-optimal).

Yes, i did. A proper design, a proper case, no hacked twitter accounts, server psu, probably only a few weeks of delays, and one fifth of the price we paid to those f. of hashfast.

HashFast has real chips working inside their properly designed high airflow proper case, powered by their proper Sea Sonic PSUs.

If only poor Cointerra had real chips to put in their box of fans. Cheesy

Too bad Cointerra's "7-10 day" push-back has now grown into a month or longer delay. So much for "mid December" and "late December." Cheesy

I prefer starting mining with HashFast hardware this year than Cointerra vaporware next year.

ALWAYS BET ON iCE...

Anybody know if the HF miner firmware can be updated by the user after delivery?

Clearly HF is rushing to get the BJ out of the door before X-mas so the initial firmware might be sub-optimal.

anything else would be bullshit

of course you can update the fw. hell i could even update the fw of my dvd-player if i would like.

Well, the BFL miners are very hard to flash. You need an Atmel AVR Dragon to do the job. So I'm looking for a software based flash solution.

If the coffee mugs were worth a damn, then they wouldn't be drinking out of a styrofoam cup. Please tell me we won't be paying to air freight coffee mugs ala BFL.

GN chip bringup - Some small tweaks to the chip power supply and we reach 105GH per die! Silicon proven good. Next step, all 4 dies running.

420GH. Smokin!

Lol. I want to know what the password was.
PSU with the airflow reversed, Twitter accounts hacked, what else?

(they already removed everything and i tried, but i couldn't open the links, probably twitter locked them)

Simpler question: Wouldn't it be plugged in in order to have network connectivity and power?

It looks remarkably devoid of any cables... Maybe it is facing front and they are all hidden in the back.

Though you are most likely right.
This is probably a case, with at best, a hash module mockup inside... otherwise you would think they would provide a link to an eligius mining address or something.

Still promising news about the 384GH/s at .74v
