Not sure yet. We had originally settled on the first one Intel put out, but since we've waited so long and we're not locked in by design yet, we'll probably pick a newer generation. Our products tend to be in service for a long time (upwards of 20 years) so we like to get as cutting edge as we can without losing a finger :) Bruce > > Regards, > Simon
