nicely done, not to mention nice cleane setup, din't have to spend on materials. very cool. i will second the computer fam, all i did is take an old cell phone charger wire it to a computer fan, i would suggest one of the larger sized fans. and go for it. very very cool. just a little info for wat its worth. i ust an old chest freezer for lagers, and even for ales to maintain temp, it can be hard to put 6.5 gallon carboys in and out of the frezzer. if you coupd, maybey you could add a stand and put in a side door? but really nice build very cool idea.
