What is the reason behind the IO bracket

This is largely just a random, 7am at work question, but is there any real necessity/utility of the motherboard IO bracket beyond aesthetics, minor noise reduction, and reducing to some degree the risk of damaging individual ports (if, say, a cord is yanked out, the metal bracket should prevent the port mounted on the motherboard from bending as much as it could otherwise)?
 
I keep mine in to help with the cross-flow air pressure from the fans (blocking air from entering there), and to reduce dust coming into the case.
 
Yes it important.

See all those springy metal that stand off on the back of the IOSHIELD that touches the motherboard? They're called "EMI springs." Their purpose is to maintain lots of points of electrical contact with the motherboard's jacks, to prevent any long gaps that would allow excessive EMI leakage (electromagnetic interference).

Is that really true? What about all the other holes in a comp case?

I thought I had read something along those lines...

At any rate, my motherboard currently doesn't have the bracket in as I was having some trouble with the new setup and left it out in case I had to do something with the motherboard (easier to pull out and then put back in the motherboard without needing got line up all the ports). I really don't want to pull everything out again (with finals week looming ahead), though I'm not sure what else I could do. I could try putting it in while the motherboard is in the case, but I imagine that would be very difficult if even possible.


Edit: In any event, I can't imagine there's too much a risk of damage of running the motherboard without the bracket, given that people run test systems outside of cases (and thus obviously without an IO bracket or anything else) without much trouble.
 
mostly you're just looking at signal interference on anything electrical, but you'll probably see it first on AM radio reception, then maybe TV/FM radio and cell phones. There's probably some legal jazz statement about EMI on one of the front pages of the motherboard and case manuals.

you really should put it in when you get the chance. You might get away with just undoing the motherboard screw that's closest and putting some pressure on the case - should give you justabout enough space but careful not to flex the motherboard too much.

Well, I have a Antec P182, so I don't think it will flex that much, and at any rate the rear 120mm fan is in the way. It might be doable, but would probably around the same amount of time as just taking out the motherboard, and thus runs into the original problem of not being able to justify doing that with finals coming up. In any case, for that same reason I won't be using the system much (I really only use the desktop for games, or Folding@Home in colder weather), so beyond dust I don't think it will matter all that much.
