putting together a computer is so increadibly simple, if you can put together a easy lego set, you can put together a computer.

As for doing this for other people as a side business or whatever, Ive done it for a few freinds and stuff, but I wouldnt do it for people that I didnt really know. Like journey said, people will start asking you tech questions. The problem is that most people dont really understand the difference between software and hardware. Hell, do you know how many people literally give away or throw out thier desktops and laptops and buy new ones. They do this for such retarded reasons, most of the time all they need is a reformat.
