The case measures 207 mm wide, 277 mm tall and has a depth of 335 mm.
So even though I know an inch is about 25mm, whenever I read an article that describes the overall size of something that isn't a case fan using millimeters I wind up reading past the dimensions without gaining any understanding of its actual size. I have to go back and convert it to inches in my head if I ever decide to really grasp its actual size. Perhaps a younger generation of Americans have been taught to think in metric, but I doubt it. FWIW, this isn't tomshardware.co.uk, so while I don't mind that fans and PSU's are measured in millimeters, when it comes to figuring out how big a case is, I'd much prefer inches (or at least put them in parentheses so swarms of idiots like myself don't all have to do the conversion separately).
