No question on price. A lot of folks just don't have the knowhow to assemble their own. Some don't have the time. As for your 166, you could have one of those house programmed computers handling everything from security to turning on the water, house lights, hot water heater ( to save money, you'd be suprised how much turning it off saves) turning on the air condidioner proir to arrriving home, ect. Another thing could be the home network base. Add a large hard drive, some memory if needed, and necessary network euipt. and use it for a storage device for your other computers. If not sure about necessary netwroking equiptment required then they make plugins to take care of that. I'm sure there are other uses but these come to the top of my head right away.
