Okay, sounds good. The bag of screws contains I think 4 small screws,
they are the same threading as the tiny nuts, and the power supply.
I'm guessing those 4 screws are to mount the power supply. In
addition to that, there are larger screws, they look to be close to
the same size that you use to screw a horizontal rackmount device to a
standard vertical rack. I'm guessing these are the M5 screws you're
referring to, that can be used to screw into the ends of the rails
They're not self-tapping though, they're just machine bolts. Also,
like I pointed out before, there are tiny evenly-spaced holes all down
the rail, those can just be ignored
