Hey all, I'm thinking about hooking up to the internet via adsl and was wondering what equipment I would need in order to do so.

If its just your one computer, the service from the company, the modem -- either via USB, or ethernet--so USB ports on your computer, or an ethernet port on your computer. It would be better to get ethernet if you can, so that in the future you want to network, you won't have to worry about leaving one of the computers on so you can get online with the other.
