Hmmm. A window unit costs less than a chiller. A chiller that's sitting in the heat isn't as effective as one that's not. That's why most of them aren't designed to sit outside.
Also it will add significantly to the overall heat in a room. I've got one friend that has a 150g in his office with a 1/2hp chiller. This is in an office building with huge central AC units. The chiller put out enough hot air that it would raise the temp in his office by 10 degrees or so until he attached some cheap ac ducting to the chiller and ran it up into the suspended ceiling. His office is probably 15ftx20ft.
I did a lot of research on them when I setup the tanks the first time. After doing a bunch of research I decided that trying fans first was a good idea. As it turned out they did the job, and cost me a lot less both to purchase and in electricity than a chiller would have.
I'm not saying he might not have to buy a chiller anyway. Just that trying the fans first might be a good idea.
