My experience is that the quoted length usually disregards the thickness of the PCIE bracket. So it's safe to assume even cards that honest to their spec should have ~2mm leeway.There's no one answer to the question of how long to design your case. It's a design balance between compatibility and compactness.On the vertical side, you want at least 30mm above the angled part of PCIE bracket, which is to accommodate cards with a single 120mm fan, and has the ATX connector at the top.
