So I ordered a few of these panasonic panaflo fans and they didnt come with any mounting screws...
I went to my local microcenter and they told me they didnt have any of the right screws I needed, though they couldnt well describe to me what I did need. I went and looked myself and bought some typical short "fan screws". This was fine for mounting the two rear fans because i could screw them in from the back through the case, and into the fan. However, I could not mount the front intake fan because the outside of the metal where the holes are is inaccessible and obstructed by the front of the case. Apparently the only way is to screw them through the fan holes and then into the case.
Is there any other place I can relatively easily obtain these screws or some other way of mounting this front fan??
