ESR, yes, the lower the better, it's kinda like inductance in an AC circuit, along with physical resistance. That's why audio grade caps have ultra low ESR, the very high end systems anyways...

That Quark looks VERY exposed! Too much for my blood!

I am going to try and make my heatsink mod get the top FET's attached to the bottom of the case for additional cooling.
