- Case: NCASE’s T1 specifications, checked October 24, 2026. NCASE (which now makes the FormD T1) lists cards up to 140 x 325 mm and 3.25 slots, with CPU cooler height falling 5 mm for each quarter slot of card thickness.
- Card: NVIDIA’s spec page, checked October 23, 2026. NVIDIA publishes the slot count, not a thickness in millimetres, and asks for room for a 3-slot (61 mm) card for airflow.
- The T1 trades card thickness against CPU cooler height: 73 mm of cooler with a 2-slot card, 48 mm with a 3.25-slot card.
