If my goal was to monitor my system (by reporting temps and tracking when things are running or not), as opposed to controlling it, what would be the easiest/quickest/cost effective way of doing this?

At its simplest, how can I get say 1/2 to a full dozen temps into my windows PC in near real-time? I work from home, my PC is running all the time (and I have remote access to it when I am not here), so if all I want to know is which parts of my system are at what temp, would my strategy be different that if I wanted to know all the temps and then make control decisions based on them?

As I head into my second season (first with storage), I'd like to add monitoring capabilities and then *maybe* add the computer-control logic in the next phase (year 3).
 
1-wire without a doubt. $30 for the usb adapter, a few bucks for each temp sensor, and free software to read the temps. 1-wire viewer is available free from the
Maxim website. If you want to log the data to a flat file/sql database there are a few free options. If you want "pre-built" sensors check out Hobby Boards @

You can save a pile of money by soldering up the sensors yourself.
