What is covered
Named ATX and Micro-ATX cases from NZXT, Corsair, Fractal Design and Cooler Master, plus generic form-factor buckets (any brand) for listings that don't name a model.
The bar on each row runs from the lowest to the highest sale counted (the figures at its ends), with the middle half shaded and the median as a dot. Each bar is scaled to its own part’s sales. How prices are worked out
