o the 10-12 screws holding the motherboard to the chassis. Again, you don't want the motherboard flapping around inside, either. A dozen screws sounds a bit excessive though.
It is, and you certainly don't need that many for your filer to run fine. You can screw in half as many if you like. But remember, Netapp has to *ship* these things, and the more screws you have, the less possibility of damage.
I have always had bad luck fitting SBus cards in Suns; I can never get them wedged into the external slots just right. And, those dinky little screws on the back are hard to handle even without having fat fingers.
Some of those SBus cards are impossible, particularly when they are 3rd party and don't *quite* fit exactly. Screws? I just skip 'em.
