Hey thanks for the response guys... I actually did some more checking on the web for mini-AC units and they have some that are made for computer equipment that are only 200 btu which is more than enough for my tiny box.

They are only about 10 pounds and they are about 5 inches wide by 7 inches tall by 7 inches deep. I think that this would be Ideal.

I hope this will help someone else in my situation.

Good luck:thumbsup:
