Only Two Diagonal Holes For mounting rear Fan

[TheITLguy]

Hi,

i got an weird situation (maybe)
My PC cabinet have only two diagonal mounting holes for Exhaust fan at the back.
can i really install a fan there?

here you can see pic http://imgur.com/pLAc9tM and http://imgur.com/L1IbGQo

Before buying any fan i just want to confirm that is for fan mounting.
it looks like i can mount either 80mm or 120mm fan there.

It would work with two screws, but would bounce around a lot. It looks like those dimples were ment to become more holes, although I'm unsure why the manufacturar wouldn't just put the holes there. Maybe try taking a pen to puch them out

can mount a fan with only 2 screws have done it before when lost 2 screws

i just put rubber washers under the other 2 corners to stop any rattle/vibration

but as said you may be able to punch/drill those other 2 indents out
