** shop your ovens and obtain a copy of installation instructions and rough-in requirements for that model. Then go shop a cabinet or have one built. **
I wouldn't make any final cabinet cuttings until you have the product you're going to install in-hand.
I have heard of cases where the model specification had changed slightly (that right reserved by the manufacturer as noted on most printed material) on the models currently available when the purchase was made which caused the consumer some headaches (and added expensive) when finally trying to install a product.
