Cut some holes in the tub
attach fans (see pics)
Glue in heatsink
Wire it up cut holes in lid, fill tub with water or ice, put lid back on
Turn it on
I don't know how effective it is yet because it's been cold the past few days.
(With a molex socket you can make it run from a computer)

(And, please can we have some in-focus photos?)
when the heat-sink has warmed up I would change the water / ice.
