well if they have a hole for a screw then you can probably re-use those ones if you need to
Yep they do, each one has their own screw for the Pavillion a804n case. However, on the case im using now, it uses 1 screw to hold them all in place. So i guess i should be good to go, that was really my only problem with the CM Elite 430. Thanks guys for replying.
