Ask Slashdot: Wooden Chasis and EMF

Red Leader asks: "Hi. I'm writing in the hope that some electrical people will be able to help me out with the nitty gritty aspects of shielding a computer case. You see, I'm building myself a computer case out of wood. I have already built one, but it was merely a wood case (replacing the plastic) which overlayed a standard metal chassis. Well, that was too heavy, and I also want to use my own layout for the 'guts' of the box. So aside from heat, noise and grounding (which i've pretty much figured out) - I'm worried about the electromagnetic interference aspect of this new machine. It's most likely going to be a dual Celeron based Ultra-Wide SCSI2 system - which I think (!?!) will generate quite a large electromagnetic field. I've been thinking of shielding the case by lining it with this with copper fabric or something similar - but don't know how it sizes up to a solid metal case. Any help would be greatly appreciated - and I'll be sure to post pics of the case (well it's actually more than that) in progress and when completed.
