Installing Halon Fire Supression System at Home?

swmagazine asks: "The house my family is building just burn down 2 weeks before competition. Now that the insurance is paying out some money, I am seriously considering installing Halon system at home because the house comes with a server room and I will be having at least 10 computers running in the house. I would like to know if anyone has experience with Halon system as well as the feasibility of installing such system at home." The possibility that your computer could conceivably be a fire hazard is extremely low on newer machines. Older machines, without the proper protection, may overheat, and that might cause problems. Might such a system minimize the damage posed by a house-fire, or are they too expensive (or too ineffective) for the average home owner?
