Well, I removed the shiny sheilding plates in the display's housing (three peices in all) and it looks Very cool...
theres a similar sheild in the main body's housing, but is heald with small plastic pins that have be melted flat to rivit the thin plate to the plastic. The question is... is this peice holding any parts in, such as the trackpad? because theres quite a few mounts for a peice that dosent do anything. But i need to remove it to complete the look

I still don't have my iBook yet (hoping for January), but I do have 2 cents to add...

This is probably already well-known, but the metal shielding is there for a reason. The FCC 15 class B stuff, about interference. The various clocks running in the computer (all computers) are at radio frequencies. That shielding is required for them to comply to FCC regulations. Without it, you may (maybe, maybe not) either start receiving interference, if there is a strong RF source anywhere nearby, or likewise, could start causing interference to others.

Without the shielding, for example, you might start noticing the computer crashing inexplicably, or acting wierd, around RF sources. Like flourescent lights, FRS radios, etc. etc.

FRS channels 8 to 14 are between 467 and 468 MHz. I wonder if that might have any affect on an unshielded CPU running at 466 MHz.

Then again, there may be no trouble at all. Obviously though, Apple didn't put the metal shielding in because they thought their laptops were too light, or didn't look cool enough without it.

Again, just my 2 cents.

Well I pulled off all the sheilding in the display housing and the top part of the main housing. Damn it looks COOL. I determined that the sheilding does little to nothing as all the boards are still sheilded by the aluminum covers and the sheilding under the logic board. as for the display, the back of the LCD seems to have sheilding (perferated aluminum sheet).
Plus, i dont think the new FW iBooks have this sheilding in the first place... they have an opaque white casing rather than the translucent rev A. I dont see why they'd do that except to exclude the sheilding peices.
