The original NZXT H500 allows a CPU tower up to 165 mm tall and supports ATX, Micro-ATX and Mini-ITX motherboards. That makes clearance, RAM height and socket hardware more important than raw cooler size. This guide focuses on current air coolers at or below 165 mm; a 165 mm model is a limit fit, not extra clearance. The H500’s top is for one 120 mm or 140 mm fan, while its front cooling clearance is 60 mm, so do not assume the later H510 or H5 layouts apply.
