In order to house the new modular platform, Intel's upcoming Ghost Canyon mini PCs will feature the largest NUC enclosures yet. This also allows for improved cooling, and it looks like Intel has also modified the layout to include a small backplane that houses the "Element" module and can support a discrete GPU and an NVMe SSD. The "Element" module itself can be powered by laptop-grade CPUs like the Core i9-9980HK, Core i7-9750H or Core i5-9300H models.
