I might be interested. My A4000T is my main computer, but I'd like to do a few hacks, and having a spare around would be handy for sizing things up before I tear down the "real one", and for sizing thngs up during idea sessions when I don't want to tear the "real one" out at all.
I'm currently using a spare A3000 desktop to build my tower hack without interfering with usability of that "real one", which is quite useful.
