Sounds like a shlemiel field to me. I can't wait to hear how this one turns out.

It could be a shlimazl field as well. But that's just what my friend LaVerne suggested.  ;D

GoPodular.com:

I was thinking about this today and don't those anti-static bags you get electronics equipment in operate just like faraday cages?  Might be able to put the mobo in a case and then cover the case with some of them taped together.  You'll have to pipe in some fresh air for the fans though.

JustMichael:

FrizzleFried, do you happen to live on or near a military base?  The reason I ask is that a lot of the frequencies that garage door openers use has been allocated to the military now by the FCC.

daywane:

you can send the cab to me.
My house is on a slab foundation, and made of cinder blocks, and stucco over that

I can not get a signal into my house let along one out.

SavannahLion:

You have to have a case in order for a motherboard to qualify as an FCC Class B device. Those cutaway side panel with plexiglass windows or those whole plexiglass cases don't pass FCC testing, so don't bother using them.

This paper has a nice description on how to handle and reduce EMI fields http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26003.pdf
It points out some details even I wasn't aware of. Such as it's the length of the gap in the case not the width that causes problems and grounding heat sinks.
