It is my understanding that your chassis ground (case) is an electrical reference point. nothing more. If you decide that your chassis is going to be a metal grate nailed to your wooden case, that is fine (or just use a nail). Connect the ground wire from your power supply to your chassis metal grate (or nail) and anything else you want grounded. This grate is then your ground (or chassis or electrical reference point). The chassis ground for those who don't have a case is the metal ring on the end of the ground wire connected to the power supply.
The bottom line is that it is not manditory to have something to connect it to (though it can be handy). You can leave the wire loose if you want (but anything touching to it is then grounded).
Make sure you are consistant with your ground (do not have multiple chassis points. you can only have one reference point) or you may run into problems
As far as EMF goes, I don't believe it is that huge of an issue unless your circumstances are unusual. The EMF generated by your computer is so small that it does not interfere with itself or other equipment around it. AFAK.
