AMD no longer mandates that the holes be on the board. The LanParty NF2 isn't the only board without them, though it seems to be the only 'top-end' board without them.
They know from customers and reviewers that the mount holes really should find their way onto the next revision, so we'll wait and see what they come up with =)
this board does do just as well with a high end clip-on hs like an SLK-800A/900A, and performs extremely well with an SK-7 on it also.
