Any ideas/suggestions for cabinet kegerator?

I've got a built-in china cabinet type thing in my kitchen, and i would really like to turn the lower half into a kegerator. Its about 48 x 24 x 36. I was thinking i could line it with insulating foam, but not sure how to chill it. do you think i would have a condensation problem? any advice or suggestions would be appreciated. cant post a pick because im online on my Wii until computer gets fixed.

thanks in advance

First....do you own your house? Condensation can cause some serious issues with rotting out your walls...be careful! Search "fermentation cabinet" and you should find what you need.
