how many standoffs needed for motherboard?

How do you compensate for the height of the threaded end?!

I flip it around so it sticks through the mobo, and I use a nut
instead of a screw to hold it to the mobo. Or I'll use a plastic
standoff and cut it off at the bottom. Also electronics parts stores
and hardware stores (real ones, not home centers) sell brass and
plastic standoffs in several sizes and styles, including some with only
threaded holes. They also carry plastic nuts and bolts.

I said putting standoffs in the holes in the "case" would create
problems. If you put standoffs in every one of the holes in your case
and then put the MB in, I would sure like to see it run without
shorting!

No, what you did was exclaim, in response to the first posters advice of
putting a standoff "under each hole in the mobo," and I again quote,
"Shorting out the motherboard is exactly what this advise will do!!"

Which is why I asked how you figure a standoff mounted 'under a hole' can
short out to anything on the motherboard?

That's a TERRIBLE idea!!

Standoffs come in different heights...depending on the manufacturer.
The height of the standoffs determines the height for the cards.

Put the wrong standoffs in...and yer askin' for trouble.

Have a nice one...

The standoffs come with the enclosure. The mainboard manuel will
denote where board should be affixed to the enclosure.
All of the above info can be found on the mfg's web page.

Once upon a time I used to buy wide nylon bushings from the hardware
store and press the standoff into the center of it. It made for great
physical support and if the standoff was a little short it didn't make
any difference as they sold a wide range of bushing sizes.

Exactly.

You should use ONLY the standoffs that come with the case...unless yer
a seasoned installer and know what yer doin'.

Most folks don't realize that standoffs come in different
lengths...and they'll simply use some spares they have layin' around.

Not a good idea.

I think we get the picture! lol

I appreciate your warning me, but your phrasing makes it sound like I
would take his advice and use it poorly.

I've put casters on legs and I've put legs on tables, and I understand
the concept of having all legs the same height.

If I were stuck with one that was too short, I'd use a longer screw
and then a nut or a couple washers below the mobo to reach the right
thickness. But more likely, I'd buy some.

Exactly.

That only works if you have the standoffs that came with the case.
This is a used case and I don't have them.

I've got to disaagree. The length of a stand-off is not hard to
discern like is the difference, for example, between PNP and NPN
transistors.

Most folks don't realize that standoffs come in different
lengths...and they'll simply use some spares they have layin' around.

I'm not dumb enough or blind enough to not notice when things are
different lengths.

Not a good idea.

And also to you.

Then how do you know yer usin' the correct length?

If they're ALL the wrong length...yeah, they'll match! lol

How many stand-offs, or whatever those posts are called that screw
into the case and the motherboard is screwed to them, are needed to
hold a motherboard? This one is an Asus board with an 800 Mhz CPU
and 3x3 array of holes for mounting, plus a small 2x2 array of holes
around the cpu.

A very generous friend gives me his old computer parts, and I thought
I was ready to assemble the computer today, but I only have 6 of those
screw-in legs. I'm going to put the memory in and the cpu fan in
before installing the motherboard, so can I skip the middle row of
screws and the 4 surrounding the cpu? If later, I want to add more
memory, can I do this even though the legs aren't there under that
part of the mobo?

I'm afraid I'll install with only these 6 in the row near the back and
the row nearest the front of the case, and later forget the middle row
of support isn't there, and damage it.



The motherboard is an Asus A7M266, in case there is anything special I
should know before using it. I bought a DDR DIMM, so that's not an
issue.

Thanks.

6 will be ok though I would make sure 1 of them was in the closest
official spot to yer memory slots ....... you said you set up the board
before casing it but chances are pretty good you will be changing memory
at some point or even swapping current memory slots even sooner .. n
that's when ya sometimes push down pretty hard on the board in the case
....

6 is fine though .. no problem

When the board is the right height to fit well into the holes in the
back of the case, the standoffs are the right length.

If they're ALL the wrong length...yeah, they'll match! lol

You too.
