That's pretty cool. Probably easier (and cheaper) for them to get you to check the fit than to try tracking down either a case to check or detailed schematics.Last week, one of my 230mm case fans started making a horrible racket. Googling suggested Noctua's 200mm NF-A20 might work, but my case (CM ATCS 840) was not listed in the compatibility chart. Acting on the advice at the bottom of said chart, I emailed Noctua... I received the UPS tracking number for my free NF-A20 fan* this morning. Package is suppose to arrive on Monday, so they did not skimp on shipping from Europe either.
* They did ask that I send compatibility data.
