So, I've got a case on the way. Says on the website it has One (1) 4-inch rear case fan (not included). I'd like to order a fan for it before it arrives. Does 4 inch = 120mm fan? Would stink to order a fan that doesn't fit. What do you guys think?

Can you post a link to the case? I've never heard of a case stating fan size in inches. Anyways, 4 inches is closer to 100 mm.

Thermaltake, Antek, Rosewill and others all have mid towers in that price range. I've never heard of Olivetti except in connection to typewriters. You might be better off with a known case brand.

doesn't seem to be 120mm...
seems probable that it's a 92mm fan. As ~102mm is closer to 92mm than it is 120mm

I used Paint to measure the rough diameter of the fan and the width of the case in pixels based on the stock image of the back.
assuming the case is 173mm wide (6.8") while the fan is ~144 px in diameter and case is ~265 px in width, the fan is ~94mm, which makes 92mm the likely diameter for the fan.

You could also compare it to the I/O shield cutout, which is 159mm or so.

But you're probably right - that looks like a 92mm to me also.
