Windows 7: Warranty for consumer hardware when I buy it is a business

Most hardware (i.e. MB, CPU) has 3 year warranty. Will that warranty be reduced if I buy it as a business? I understand this may differ from manufacturer to manufacturer, but I like some general statement/experience.



I'm looking at buying the cheaper B75 boards that only have 1 year warranty since they are for business. If I got the 3 year warranty for a consumer H77 board, I gladly pay the higher price. But wonder if that 3-year warranty is even applicable if I buy it as a business (and obviously for tax reasons I don't want to lie and buy it privately).

I also wonder for the rest of the hardware (but the MB is the only where I actually saw a 1 year warranty as opposed to 3 year for consumer version).

Similar problem would be if I sell the hardware to a private or business, can I claim to say it has 3 years warranty? (Obviously I don't want to learn the hard way that year 2-3 is on me if I promised 3 year warranty)

Thanks
