If you have a NAS device, many of them have a webserver built into them, so its just as easy to run your own website from home, as I do with my website on the link in my signature. I use a small netbook, but I used to use my NAS device.
You can create and edit pages with the free Mozilla Seamonkey suite.
What is a NAS device please?
Network Attatched Storage.
People use them to act as media servers to distribute video, music and other files within their home network. They are normally low power consumption devices, which are left on all of the time.
Most have webserver and FTP functions which allow you to connect to them from anywhere on the Internet.
