Actually I don't think it's much taller than a standard double oven; the configuration gives it the illusion of height.
As for oven cabinets, most lines have versions either with no bottom drawer (blank panel), or shorter doors at the top. Any of the better manufacturers make them to specifications, and have lots of modifications that can be made. For example, I have a download of the Fieldstone Cabinetry Specification Guide, and it has over 700 pages. So getting a cabinet to acomodate it wouldn't be a problem.
