REgarding splitting the power using the hack described, 160 melted minis and a halon cloud coming up.
You should have a talk with your power cord provider. You should be using cables that can handle at least 4 amps in anything with a 110v plug on it. I don't think you can buy one smaller than 18ga and those are good for 10 amps. Remember, you have to handle enough current to blow the breaker if something goes wrong (unless you are British and have your own fuse in the plug).
We went through several designs with the vendor. This cable is designed to operate at the circuit rating. The wire from the PDU plug to the split is 12GA 600V and the cable from the split to the mini is 14GA 300V.
