So I was browsing Craigslist today and stumbled upon the following ad: http://boise.craigslist.org/sys/2142530215.html Seems intriguing and really cheap. However, I'm not sure how to tell what Rev. it is? Any clues? Does this sale seem too good to be true? I emailed the seller to ask more about the computer, but haven't heard back yet. I guess we'll see!
