What screw size are the Antec One front panels?

[Detevtive Marvel]

I got an Antec One S3 and lost included screws, I'm trying to install the fan for the front panel but the screw holes are tiny

On page 7 I need the screws lettered 'E'

What size screws does the Antec One S3 front panel use?
Please help ASAP

They look a lot like m3 30mm, same screws used to mount fans to radiators
