- Motherboard Installation?

I am trying to install an older board in a atx case. The board is a
Biostar M7NCD. My question is regarding the eyes or holes in the case
for the motherboard screw's. I have 3 of the holes using the brass
stand-offs. The other three holes only 1 matches up so I have a brass
stand-off under that hole. What can I use to prevent the other two
holes from making contact with the two last eyelet holes? They don't
match the holes on the motherboard for mounting. I just don't want the
board to touch the upward eyelet's for fear of a short. Any advice
would be appreciated.
Re: Motherboard Installation?
It is a standard ATX, full width board. I don't really
understand the rest of what you wrote as any standard ATX
case should accept it, should have corresponding holes for
putting in the standoffs it needs. Maybe some really cheap
generic or OEM cases wouldn't have the right-hand side row
of holes, in which case you would put nylon riser pieces in
the motherboard holes, they look like this:
Depending on the height of your brass standoffs, you may
need to trim the nylon ones to be the right height. Ideally
they would insert into slots in the motherboard tray, or you
would drill corresponding holes in the motherboard tray then
(since it is nearly impossible to tap out treads on a
motherboard tray after drilling, opposed to the factory
method of intenting the metal so there is more there to tape
a thread into) insert the standoff through the hole and put
a nut on the standoff on the other side- tightened VERY
tight so that you can tighten and loosen the screw on the
motherboard side later without worrying about the nut coming
lose. I sometimes use a drop of superglue to lock that nut
on, and it is usually 6-32, sometimes 4-40 threaded (depends
on which standoff threading you have).
??? I read this a couple times and I still don't understand
exactly what you mean. The standoffs unscrew from the holes
and are moved to where you need them. I feel silly for
writing this as it is probably obvious but I'm just covering
If you mean that you have a motherboard tray with "bumps" or
pressed-in raised areas that are meant to be standoffs, are
you sure you have a standard ATX case if they don't match
If you have some bizarre case, I don't know what to advise
as being easiest, since I don't know what the case is like.
If you can get a good picture of this area w/o the board
installed yet, post it somewhere and link it here, that
might help a lot.
IF I understand what you mean and there are raised areas
that need to be flattened, you could put the back of the
tray against a hard flat object like a piece of concrete
block, brick, iron railing, etc, and use a hammer to pound
out the raised area. If you can't or don't want to do that
and this area might short against the board then you could
put a few layers of electrical tape over the area... putting
more layers if there are through-hole leaded components over
the area as those leads can pierce through the tape over
time if not thick enough.
You still need to find a way to secure as many of the
motherboard holes with standoffs to the case motherboard
tray as reasonably possible, I refer to the idea above about
drilling a hole, putting a standoff through then securing it
in place with a screw on the other side.
Maybe I have completely misunderstood what you meant, please
refer to holes each time based on where they are and a
picture of the case motherboard tray would help a lot but I
wonder about this case as any standard full ATX case should
accept that motherboard without any problem.
Re: Motherboard Installation?
The brass stand-offs just unscrew and you should be able to simply relocate
them where they are needed.
If some of the standoffs are swedged into the case...you can removed them
with a pliers by gently rocking on them and pulling.
If there are a few places where you need a stand-off but no hole is present
to screw in one of the brass stand-offs...
a plastic "footer" is generally ok...just as long as you have at least 3
locations to use a screw-type standoff
