- BFL said a mini rig card mines at 1.5Gh/s, therefore it will have 17 cards for 25Gh/s total (even though mini rig prototype pictures show it may have more cards, they don't show all angles).
- Each card should weight at most 1kg (heatsinks...) -- this is an overestimation, for reference an HD 6990 weights 1.16kg.
- The 1400W ATX PSU will weight about 2-3kg.
- The case and fans will weight about 10-15kg.

Therefore I estimate a mini rig will weight 30kg +/- 5kg, still kind of transportable by an adult in average shape

BFL said the mini rig weights a little under 23kg (50lb). I was close

As these fans seems to be hungry fans...

I think someone already quoted power usage on 80mm fans, its around ~1.4w, but could be 2w (depends on the model). If they use silent fans, then it should be 1.4w. So, roughly they eat 49W for an average 17 cards system.

And this one

Does this butter fly ? (device is nice and big hamburger :-)

I mean power consumption measured on input with fans running, performance, etc....

You can't count

9 on each side = 18

4 layers of 6 = 24

18 + 24 = 42

Or you're counting things you can't see (that don't exist); there aren't 24 cards. In fact, BlackPrapor is actually the winner because he's including the PSU fan.

I would like to know the WEIGHT of the mini rig.
My mining office is on the 2nd floor of a 2-story office building - there is no elevator. Cry

Do you also have no friends ? Cheesy

Maybe just not any friends he trusts to help lug 15 grand worth of gear up some stairs. Or to know where it is located for that matter. ;p

I remember a quote from Sonny about single's weight. It's around 0,5kg. Since they're essentially same in config and I'll assume rig case gives similar weight per card, as in singles, excluding PSU, so that's 8,5kg+2,5=11kg in total. I really hope they're using aluminum for plates as well.

I don't know whether it will have handles on top, but from the pictures it seems to have four vertical posts of threaded rod that appear to run all the way down to the base of the rig that could possibly be structural or used to carry it. If they screwed into a plate in the base, the plate could support the rest of the rig when picked up by those.

At 30kg how will it survive if dropped ? it's better they send the kit and we assemble.

Rjk is basically correct. The fans will exhaust from left to right (as you're looking at the front of the case.)

The PSU is a Thermaltake 1400w.

The case is anodized, so painting is not going to work very well.

Now that I see the cooling design, it makes a lot more sense to me and I think it will work better than I expected.

For those that haven't quite figured it out how it works, it seems that the fan intakes (or maybe the exhaust? Not sure which way they blow...) are set up against a metal(?) plate with holes in it, and not just spinning freely in space. That plate acts as a duct from one side to the other, allowing for cool intake air evenly across all modules, not just the ones on the side of the intake fans.

As for the exhaust, well it isn't quite as pretty of a picture as far as I can tell, but it certainly should be much less of a problem with all the fans.

I heard painting strips make the mini rigs faster.

Seriously, I don't think any miner dedicated enough to spend $15k on mining hw cares about scratches on cases caused by manual assembly. Especially when there are many more legitimate concerns to have (underestimated delivery times, suboptimal cooling design, etc).

Sadly all this shit fits together...

Looks like a great product to me. The only thing I dislike is the build quality Undecided

hate this scratches on a 15k machine. Use some tape for protection ! I hope they're going to repaint the chassis before delivery. Cry
