Well, for one, it's not worth the money. The profit margin isn't enough to mess with it. Two, the warranty. I know I can have the manufacturer do the warranty, but I'd still have to deal with it. Either by telling people to contact someone else or be expected to handle other issues. Like if the system gets a virus or is just running slow. The virus is pretty easy to explain that it's not covered and that i have to charge them. Although, I don't want to have to mess with explaining this either. The running slow, phantom problems, etc I just don't want to deal with at all. Some people, no matter how hard you try and explain something to them, they always expect so much more than what they pay for. Even if you explain what they are getting before you order it.
There's just too much to mess with. Right now anyways, I just prefer to do strictly service. I don't even really do upgrades. I have done a couple, but they were specific cases with people I knew. I don't advertise it and I don't stock much for parts. I don't want the overhead. I really just want to do service and that's it.
Neutron,
Obviously, to each their own, but just a FWIW:
I've been selling new systems for almost fifteen years, and refurbs for somewhere between eight and ten years. On new systems, I average two to three hundred in profit, and offer a two year warranty, with lightning damage being the only hardware exclusion. I can literally count on one hand the number of systems I've had to do warranty work on in the last two or three years. I do two to five new systems a month, so it's a nice bit of extra change.
