Hi i recently read an article that stated that it is possible to buy wholesale without first being a registred company.

I have an interest in buying personal cumputer components with a view to building custom systems.
I have identified a number of companies that i would be interested in buying wholesale components from.But have no idea how i would go about approaching them .

Due to the nature of my intended business i would want minimal stock .As components are very quikly outdated and replaced .
idealy i would want to build to order.
Only ordering the parts i need at any given time

There is a lot of competition in this area
so buying retail while still possible makes it difficult to make any kind of proffit.

Could somebody please offer advice on sourcing wholesale components and any other information u feel may be relivent
