I was intending to stuff one of these into a 1200 case as a low-end complement to my A1XEG4, but they're awfully expensive for a low-mid-range board. I'd rather have a socketed G3/600 for such a setup. It'd probably be much cheaper, too.
The pre-assembled dealer systems do sound appealing, though.
Once the boards start shipping, or some pictures emerge, I'll give them another look.
