not an 80mm
I have an 80mm fan "rigged" inside the case. I have measured it, but the difference between a 90mm and a 92mm is too hard to tell. I think standard case fans in this range are 92mm, but with companies that want to make things difficult to rearrange on their proprieary technology who knows. I may just have to grab a piece of paper, punch holes in it for a template and take that to my local "hardware store"and see what lines up. Eh, I will figure something out. I know I can make a 120 mm fan work with a dremel tool, just don't want to go to that much effort.
