A/C the room if you aren't planning on running the chiller outdoors. Running chillers indoor is not ideal: it gets very hot in the room, and it generates some noise (although the new models tend to be quieter).
That said, I like Teclima chillers and Aqualogics. You'll need a 1/6hp or bigger (I wouldn't get more then 1/5hp unless you are planning on a bigger tank down the line).
