Ha, nice. There are so many ways to build a decent gaming machine these days. All the things I don't like about a tower can be handled if it's off in a corner somewhere.
Then I checked and found a refurb. MacPro for $2,400. They're so well built, I'm still tempted to spend the extra. (plus the thing is small, and basically dead silent, so it doesn't need to be off in a corner)
Google is your frenemy.
