Computer systems builders conventions

Just curious,

I am looking for a trade show where I might be able to meet up with computer parts vendors for opportunities to buy bulk product direct from the manufacturer.

Prefer West coast but I can do a little travel.

CES?
World Video Gamer Expo?

any help with specific trade shows would be helpful, my googlefu is seeming inadequate to the task.

There used to be a huge one called COMDEX but it hasn’t existed for years. CES is not a good show for computers. I’m not sure there are any computer shows left in the US, though there are some huge ones in Europe and Asia.
