3d server renders?

Hello, im making a website for a client that owns a hosting company.
Now my question was where do you get those nice 3d renders of servers.
Like on Template Monster's templates.

Anyone can help me further?

thanks lewis. But not really the quality i was looking for.

actually those are impossible to find. I've come to the conclusion that either the designers at TM renders them, themselves or TM has stock images made specially for their designers. Something in that sense.

However, the best you can find is: http://www.turbosquid.com

That's the best I found.

okay, thanks
