OCIA.net takes a look at a Danger Den Custom Watercooling Kit.

The pump is actually manufactured by Laing Thermotech and is sold under the Danger Den name. The pump is similar to the previous Danger Den D4, but touts better performance and quieter operation. The pump is powered by a single 4-pin Molex connection, with a wire long enough to reach nearly anywhere inside your case. Perhaps the best feature of the pump is the adjustable flow rheostat, seen below.
