When I mention to people that I build my own systems, they sometimes suggest that I make a side business out of it or ask if I'll build a system for them. I've thought of it too, but would want it to primarily be PC sales and not find myself in the long-term tech support business. I'd of course be happy to offer support for maybe three months that would cover failure of the hardware or software I installed. What I don't want, but would undoubtedly face, is dealing with people who are disasters with their computers and need a 24-hour hotline in case the computer magic stops happening. As it is, I have a few family members who take for granted that I'm only a phone call away. Is there any business prospect of building and selling system while keeping the tech support obligation to a minimum, or do computer sales necessitate a commitment to long-term support?
