Our fairgrounds had a model train show and i was able to pick up the transformer for 3 bucks, spent 1 buck on a 5/8ths dowel rod from walmart, and 1 buck for the 7 by 7 plexiglass.
the other plexiglas piece i had and i put it all together with hot glue. The magnets and fan came from my old comp, and the 3 inch bolts came from the garage.
what do you think? This was my first do it yourself project.. next is a counterflow chiller
