alot of money? 10$ a month?
You are talking about a ton of work to save $100 a year. You could pay for that by going out to dinner 2 or 3 times less that year.
Look all he asked is if it were possible and how to do it,
I'm providing advise based on those answers.
oddly enough he'd have to go through the same steps of setting up a server if he decided to buy a rack in a data centre and fill it up with his own servers.
or he could go the really easy route of just buying hosting.
which, yes, is a lot easier, but doesn't leave a lot to talk about.
try to remember that this thread isn't just going to help out 1 person who wants to know how to set-up a web server, there will be plenty of other people who may want to know.
