case and motherboard problem

[gemstone]

I am building a computer from old parts for my son. The only thing I had to buy was a cheap generic case. Well the case is a problem. It does not have standoffs. It has raised "bumps" (don't know what to call them) where the standoffs would normally go. If I put standoffs in these "bumps", the motherboard will not match the faceplate. It matches perfected without the standoffs. How do I install the motherboard if it is not supposed to touch the case?

Thanks for any help,

Wendy

It's probable that the bumps are in place of standoffs - just place the motherboard on them, and screw it down - yes, with the motherboard touching the case.
Any motherboard I've seen these days has a ring around the mounting holes. The only thing that's really not supposed to touch the case would be the traces and electrical components on the motherboard. I have 2 PC's with this kind of raised-bump mounting method (also have built a PC for someone using this kind of case) and I haven't had any problems yet.
The ONLY issue I can think of would be if the bumps were at places where there are no corresponding holes on the motherboard - then you might have to attach a fiber washer to the bump, but I doubt this will ever be the case, as case makers will want the maximum physical compatibility from their products.
