NCASE lists 280 mm for cards up to 60 mm (3 slots) thick, 290 mm with the front I/O ports removed, and 322 mm for cards up to 45 mm (2.2 slots). Height is 140 mm mid-card, 130 mm at the back corner and 125 mm past 280 mm of length; we use the corner figures.

NCASE asks for 15 to 20 mm above the card for PCIe power connectors.
A 25 mm bottom fan limits the card to 2 slots (42 mm); a 15 mm fan to 2.5 slots (50 mm).
