1) those things are F'n huge! but, for a case, I was looking at my subwoofer with a sneer on my face, what about a wooden box? make it look sylish
2) Rotor, do you seriously have to water cool ever single little part (ok, dumb question) but the mosfets?
I feel a little twitch inside me, all of a suddon, I am going to start planning a better system (looking at fridge cooling a rad, just because all this other Tec PS stuff is waaaayyy over my head, and something tells me but discharging one of those caps into you hand... I'll quote many people on this one
"Shut up foo, or I'll pop a cap in your ass"
