I'm terrified to buy the s1, I was reading the set up and trouble shoot and now I'm worried I won't be able to set it up....
It's really easy now. Early models required some custom wiring for the power, but no longer - the power connectors are just standard PCI-e connectors. Your Power Supply (which you need to buy separately) will come with plenty of PCI-e power cables, the S1 needs two of them.
