You intend to host this box at your home? If it's going to get the amount of users (and therefore traffic) that this site does, I hope you've got a hell of a connection and don't intend to use it for torrenting or anything else. A home connection with the normal 1mb upstream is not going to cut it for anything beyond a basic html site
Do you know how to set up proper DoS/DDoS protection and know server security? May want to look into a UPS for the server if you intend it to have 99+% uptime.
