Apple ships Xserve :
>Apache Web Server -- Xserve can support 60 percent more connections on an Apache Web Server than an IBM eServer x330. Under industry standard WebBench performance benchmarks, an Xserve running Apache on Mac OS X Server can support 4,051 web connections per second compared to 2,547 connections per second on an IBM eServer x330 running Apache on Linux. Xserve provides an affordable and robust server platform for even the most industrial strength web applications.

Good luck,

Bit off topic, but XServe has a very smooth look to it :D

A little while ago, Spymac (http://www.spymac.com) published a "press release" of XServeRack (http://www.xserverack.com) who announced in vague terms the intention to offer hosting on XServe boxes. From looking through the forum on their site, I got the impression that they don't exactly know what they are doing, but who knows, maybe I'm wrong...
