Any heat source in a confined space can be potentially dangerous. However when regulated and monitored they should work great.

A closet (depending on size and location), is a great place for a rack setup. You are insulated on 3 sides, and depending on where the closet is located, it could actually be warmer and maintain its warmth easier and using less electricity.

A basement closet however, may have some issues. A small stand up heater, regulated, can warm up the space pretty quickly. But being in the basement, the heat could quickly leave the area, and it would need to be heated again.

Also if the closet has a light in it, you could possibly use a heating buld, but I would MUCH rather opt for the regulated Flexwatt, since some have had issues with the bulbs.
