Fishrrman is absolutely correct.
In case you haven't done a special-order before, it is extremely easy and convenient - nothing to shy away from. You can easily configure the iMac the way you want it on the special order website. The costs of all the options are clearly visible. Unless you order right after some sort of big upgrade announcement, the delivery time is very reasonable. Typically less than 10 days from order to getting your iMac. You also have the option - at no extra cost - of having it shipped directly to an Apple store. If you have a store near you, this particularly convenient as you don't need to worry about managing Fed-Ex deliveries to your home. Apple doesn't charge your credit card until they ship, and there is excellent tracking and notification about the status of the build/ship process. You can also cancel your order or change the configuration any time before (or 2 weeks after) delivery without charge. Overall, a delightful customer experience that I highly recommend.
