Sounds like the Jupiters can possibly be upgraded to 800GH+ with two more cards. No room in the case though.
I think the case is pointless anyway. They should of flat shipped it and just let us put on the heatsinks. The way they slap on the fans (and how they fall off) I wonder how great they paste and mounted the heatsinks. I have very different temps on mine.
That could mean a lot of things of course, but it would be one less thing to wonder about if we assembled most of this ourselves (and would of gotten mine a week earlier no doubt)
