I'm looking for a place to buy some more servers pretty soon (in a month or two), and I would like some suggestions on where I should go.

This will be a multiple server purchase, (1U & 2/3U) and I would like a company that I can form a relationship with (ie, order servers on demand from them)

I've heard a lot about rackmounts etc, but their site is kind of under the weather...

Are there any other places people know of? I'd like to shoot for the $1000 or less range.
