Butterfly Labs - Bitforce Single and Mini Rig Box

[Garr255]

I'd recommend high rpm small fans blowing in the gaps between the singles, and low rpm blowing out the other side.

Ah OK, I hadn't seen the Rev1 show in the pic, I was thinking of the original board with undersized power, that must have been Rev0.

EDIT: Does Rev3 have feet on the bottom? It looks raised up a little bit.

Yes..  true, Rev0 existed as well as a discovery prototype. 

Rev3 has feet...  4 soft rubber nubbys.

Cool - I see that would enable stacking to some degree, but how would you recommend the cooling to be applied? It seems that the air blowing from the top of the lower device(s) would be brought into the intake of the upper device(s) if they were stacked. Or does this generally not manifest itself as a problem? Perhaps for a tall stack, a small fan of sorts could blow up the tower from one side. Stacking even 10 of them would be about 700 watts of heat to dissipate.

I wouldn't recommend vertical stacking without spacing in between.

Here's another view of the Rev3 board & heat pipe system.

I count 26 singles (one of them with my name on it), and 26 x 832 MH/s is 21.6 GH/s.

I count 25 singles (one of them with my name on it), and 25 x 832 MH/s is 20.8 GH/s.

The ones in the rear of the pic are double stacked.

OK, you may be right: 35 x 832 MH/s = 29.1 GH/s

Trying to see what fans they are using 

Power Draw, CFM, dBa ...

And while we are at it, does anybody know the data (draw, CFM, dBa) for the Rev2 unit fans for comparison (if not same)?

[SgtSpike]

BFL - it looks like final assembly is done in-house?  How many units are you putting out per day now?  And how many units do you have on backorder?

[Garr255]

Ahh these look so sweet. I need a car more than a single though

Get a LOAN for the car, buy a few singles and let the singles pay the monthly car payments...

OPM other peoples money
+ cashflow

Looks like the Rig Box is no more. RIP. Looks like they replaced it with the Mini Rig, which is now on their product page.

[bitpop]

So it will be 30 singles and use 2400 watts not 1200

I don't see that picture there. Where do you find it?

Is it just me or is this "prototype" photoshopped?

I actually find these 4 points a bit questionable:
