It's actually an interesting design, but really all they did was take two workstation cards, a xenon processor, and 4 sticks of ram and put them into a aluminum case with only one heatsink and a fan.
The single heatsink is the only terrible thing, and I'm going to go ahead and assume that they're going to sell it for 2-3x normal part markup prices. This is the closest thing apple has come to an original desktop, however, so good for them
