Well, I checked the prices with the combos/free shipping on the case, it comes to just shy of 750 bucks, minus 30 bucks in MIRs. Not a bad deal at all for that machine. If you take out the 4670 (you can always upgrade later, and the onboard is pretty adequate for the time being), it would be just shy of $670, minus 20 bucks in MIRs. Dunno what kind of deals they will have later, but that's a machine worth pouncing on.
If you have any other questions, feel free to ask.
