I provide solutions to computer hardware problems, as well as build new systems for customers tailored to their specific needs and budget. If it's not working properly, I can find out what's wrong, and fix it. If you decide you've had enough, and you want a new, custom built system, I can do it, and most importantly, make it affordable, and that means that I refuse to charge a mark up on parts. If I had no influence on the manufacture of the component, then I see no reason to charge a customer any more than what I would pay for it myself. That's what makes me different.
