No. Also there is no 64 bit ARM hardware available to anyone (if you ignore the extremely locked-down iPhone 5S). I have used a bunch of ARM servers, but unfortunately I'm under NDA.

However there is interesting hackable ARM hardware around. I would recommend looking at the CubieTruck, Mele A1000G Quad (make sure it's the "Quad" variant), and possibly the ODROID-XU. I write about these and others on my blog (https://rwmj.wordpress.com/)

The heck with the prices. They not only won't tell you how much it costs, they will practically come right out and tell you that you, as one of the Great Unwashed, will never be able to buy one of these. Because they won't sell to you, period, for any amount of money, unless you're some kind of incorporated fictional creation that's willing to enter into all kinds of onerous contracts before they're even willing to speak to you further.

It depends what you mean by a server: the Utilite http://utilite-computer.com/web/home with its dual gigabit Ethernet ports might be enough for some applications.
