I would like to clarify this - Top: 2x 140/3x120mm in casing specs. Does this mean for top panel I have to insert two 140mm fans or three 120mm fans? Also can you please help me to understand what is the difference between 120mm fan and 140mm fan.

Yes, for the top panel, you can put either two 140mm fans or three 120mm fans. in this case, three 120mm fans are already included with it.

A 120mm fan is smaller than a 140mm fan. the numbers 120 and 140 refers to the diameter of the fan. generally, the bigger they are, the more air they could move, so they would spin less, and so your system is more silent.

In this case they have included three 120mm fans on front panel. Check this video --> https://www.youtube.com/watch?v=1_FilIuvHz0

But there aren't any top panel fans. What would you recommend. two 140mm fans or three 120mm fans?

My bad, I read it wrong on the last time.
They have included three 120mm fans at the front and one 140mm fan at the rear.
You could easily screw them off at put them at the top, or you buy some.
Personally, i see no difference in having 2 bigger or 3 smaller fans.t
