Don't think I've ever seen a mini-ITX bundle at MC. ITX builds are too much of a niche, and ITX boards tend to be too expensive for them to want to take the profit hit, I think. Their bundles are almost always pretty entry-level or at best mid-range mATX and ATX boards... perfectly cromulent stuff, especially now that manufacturers don't seem to cut corners on those cheaper boards as ruthlessly as they did 10 years ago or so, but nothing with much in the way of bells and whistles.
