I have a BFL 30ghs too, but I'm waiting on more cables to power it from the S3+ power supply.
It melted a pair of pcie cables already from my standard PSU.
None of these will ever ROI but it's fun to tinker with them.
I have 13 333Mhs block erupter too.
Final setup will change when I get the USB doctors,then i'll make a permanent holder for the compac sticks with improved cooling.
At the moment it's WIP.
I don't really care about electricity as I already have a bunch of computers running 24/7.
I also have 4 dual xeon servers and a 65Tb SAN array running once in a while (in the black 42U rack you see on the right in the photo)
