You can't cool a TEC with it, but maybe a traditional watercooling loop on the hot side and then just use the cold side in a chiller to cool the ambient water in a submersion fish-tank PC?
Going further, you may be better off just submerging an Arqtik chiller in a tank of mineral oil, leave the cold side loop output open, and keep the hot side isolated with a separate external radiator standard WC setup.

I was thinking that the OP meant to cool the tec with a waterblock, while keeping other chilled with the mineral oil, while avoiding having to insulate the board.
My concern with this setup was the oil getting cold enough to form condensation on it's surface directly, which being denser than the oil, would sink, and gradually pool at the bottom of the tank until it shorted the board.
I suppose a valve could be placed at the bottom, and a gap left at the bottom of the tank, so any condensation could be drained, without losing oil, if it reached a certain level.
