If you want to get into the computer hardware business today, it is not all that rosy as it might seem. What is enjoyable for the enthusiast who builds his own computer is not necessarily profitable if you do it on a larger scale for others.
The reason for this is simply that the market today is saturated with companies such as Dell that sell computer systems at prices that an average small business computer store owner simply cannot beat.
So if you’re getting into that type of business, it is much better if you think about whether you want to specialize yourself in the field. Rather than trying to sell computers for the average Joe, it could be a much better idea if you target a special niche market such as gamers and computer enthusiasts with your computer systems.
A gamer or enthusiast is likely more willing to spend good money on a high and computer with the best and fastest hardware. If you can establish your PC business in this sector it may actually make some profit which would otherwise be very difficult.
There are other potentially good ideas for computer businesses as well that you should look into. Good examples for this would be custom case designs and modding, gaming console modifications or similar.
Just don’t make the mistake and think it will be as easy as buying PC parts, assembling computers and selling them for a good price. This simply won’t work today.
