Xr30 G3 case screw size

[ntec]

Hi, i bought a used xr30 g3 that is being shipped to me and it's missing a couple of the corner screws that hold the case together and also the fan screws. Anyone know off hand what size m?x?mm screws it uses? I guess i can just wait till i get the light and unscrew and measure the existing screws but figured someone may know off hand now.
