Mobo replacement: missing standoffs

So I'm attempting to replace the mobo and CPU in my 5-yr-old Antec case. First time I've done this. I got everything out, but when I go to install the new board, I find that the instructions call for 8 screws and standoffs, but my old board only had 6. And of course the new board didn't come with any hardware, other than the plate for the ports in the back of the case.

I tried to get some today, but failed. (Radio Shack misled me to think they could provide some, and I didn't find out they were wrong until other stores were closed. I'd like to get this system built this weekend, everything's closed tomorrow here.)

So a couple of questions:

First and foremost, can I safely install the new board with fewer standoffs than is called for? 6 instead of 8? I guess there will be more flex than we'd like, but how big a risk am I taking?

This is my board:

Second, if that's not a good idea, do laptops tend to have mobo standoffs in them? I have a old dead Compaq laptop lying around waiting to go to the recyler. I could scavenge it for parts, but don't want to take the time to pull it open if it doesn't use the same sort of hardware.

Thanks!

6 standoffs is plenty for mounting a new board as long as they all line up. Leaving some mounting holes open won't hurt anything. Use the front 6 holes and leave the back two open.

I don't think I ever received stand-offs with a MOBO. I Believe they always came with the case.

OK, good to know.
What's front and back here? You mean front as in front of the case? So leave the holes open that are near the I/O ports? Won't that mean more flex when plugging stuff in?

Front is by the ports, when looking down at the interior of the case, as the ports face forward when mounting a board. You can use those small paper washers with the mounting screws if you have them. For standoffs, case hardware bags of screws contain them, but radio shack won't carry this. Newegg or Frys electronics will. But you don't really need any more.

OK, here's a diagram of my board showing the holes:




So you're saying I should leave off the 2 rightmost screws marked with arrows? My concern there is that they seem to be supporting the area containing the memory slots. I can install my RAM before installing the board (if that's safe to do) but it's likely I'll be adding more RAM down the road. w/ those 2 screws missing, will installing RAM in the mounted board be a problem?

Thanks again!

My most recent build had a motherboard that came with a few extra screws and a few exrtra standoffs. Not a complete set, but a few extras.

There is that potential. The board will flex more. If you choose this route, you will need to be more carefull working with the board once installed. But its not that unusual. There are some boards that come with just two rows of standoffs.

If you google "motherboard standoffs", you can find listings all over the place for just about anything you'll need, even plastic ones.
