My friend works as a freelance IT consultant for small companies and businesses who could not afford to hire a full time IT guy to maintain their computer systems.  Since a lot of business now rely on computers for increased productivity and ease in working, he has become in demand.  He prides himself for using only IBM iSeries Servers for all the network setups that he has done.   

But even with that, his clients are still happy with his services because he uses used IBM servers which are priced way lower than the brand new ones but still have the same computing power. They get to use an IBM setup without paying a lot of cash.   So far, he has not given his clients a headache because he only gets his computers and servers from reliable sources that sell high quality refurbished computer parts and components.  He shared that you can have a full IBM setup without having to spend thousands of dollars.  The cost of 1 brand new server can already get you the whole system when you go to his supplier. This is what his clients are looking for.
