LOL funny responses, but here are few more, dare I say, productive uses for it
1.) Who doesn't want 2 monitors? I know there can sometimes be confilicts with applications, but ...
2.) Dump it in storage, never know when you might need to make a headless machine not so headless
3.)Donate it to somewhere
4.) find some freinds that want it (I know one person that keps his car full of random old computer stuff and is always looking for "junk")
