Almost there:
so all this is in that case is a updated version of the first Gridseed , wonder if we can upgrade the Gridseed g- black with this all we would need is boards that fit those Heat sinks ). if it Plugs in the same way
etc .or some one fits boards for those heat sinks etc..
That boards looks about the same size as the Gridseed g- black boards, i know that's just a test board.
I don't know for the G black (still haven't got one in hands), but the heatsinks on the G blade are designed to dissipate something like 200 watts.
From what I can remember, my first fully overclocked G-Blade was drawing 350-400w.
With SF3301, 200 watts would be 5-6 chips hashing at a total of 400-500GH SHA, and 10-16MH scrypt on each PCB.
The number of chips on board is probably not high enough to make it economically interesting for the end user, but it can be done.
My dev board is 150x100mm
