I'd just run my VPC w/ 2K3 EE Server(MSDNAA is great) or run Apache off my Linux box. But for some reason I've set it up where a 3 person office has 7 computers and I'm tempted to buy another as a dedicated file server for my next project.

This is also assuming you're not running the awesomely slow DSL connection that Bellsouth peddles as commercial broadband. It'd cost $700 a month before I'd get anything close to enough to host a standard website on site.
