Ok, i'll port over any bits of crucial information that happened over on the other forum so that everything is updated here.
Regarding the two questions above. The double scroll is a hub into which you can plug two miniplanes, with this you will only need one ATX power supply and one USB connector to run 8 boards. So yes, the ATX connector powers the boards, no need for plugging in individual power to each board. The power for the boards is 5V. Effectively this means 8 boards becomes one miner. Without the double scroll, 8 boards is two miners. Yes i guess you could get someone in China to make a power splitter for you but i can't really comment on this and don't specifically recommend it, but by all means, if you can get that done, go for it.
Will bring across other updates soon.

Are the miniplanes and doublescrolls pulling power from the 12v rail and supplying the 5v power needed for each board? If so all of my questions are answered and we are golden. heh..
The problem I'm worried about is if the miniplanes and doublescrolls are pulling power exclusively from the 5v rail. We are going to run into some power issues if that is the case.
Thanks!

The power will be coming purely from the 5v. Adding covertors to step from 12v to 5v is also possible. Something like this:

Should be plenty for a full miniplane, potentially enough for a double scroll too, though you may need up to 50A for that. I've asked Dan our main hardware guy to send me through some real solid details on the power sitch and i'll post them here once i have them.
I just posted this over on the other forum:
The power for the 8 board is 25-30W. The full miniplane is ~100-120W. The full double scroll is about 250W or thereabouts, about the 5V section of a standard 500-600W power supply. If only running one miniplane, almost any small computer PSU should handle it. Id put it at about 5V, 25A for a miniplane. 450W is the cheapo power supply that can be gotten anywhere, this should be OK as long as the 5V does 25A or more.
Dan is saying that any mid sized power supply with an ATX should do the job.
Hope that helps. I'll post more as soon as i know.

Here is a bit more power information for you:
All the 5V pins are connected in the ATX. Standard ATX24 pin layout. Recommended to connect to all 5V pins to support the current.
All grouund pins in the ATX connector are connected. Recommended to use all ground pins to connect.
Estimated that each 8 board will consume up to 5A max, unconfirmed. Will need to test with hashing.
Using a 5V 25A power per miniplane you should be good but need to test the hashing first.
Running at lower hash rate will reduce the power consumption.
Any stable regulated 5V supply should be OK. So its OK to have a converter going from the 12V from an ATX to make 5V for the boards.
