I would like to build/buy a laptop or computer that I can resell to my coworker. I don't mind it being recertified. I prefer laptops, but if anyone knows a place where I can currently get good prices on desktop pc parts then I will go with that.
I can see building a system and making a little money for the time you spent building, installing software, and testing the components. I do that all the time. Buying a retail computer, not modifying anything, and selling it for a profit is pushing it.
