Is it possible? Right now I get a high of 87 degrees. Is that the lowest temp?
Of course, normally it'll run at 109, but...hehehe.. with my whole case being off fro the past few days, its..uh.. pretty cool. ANd pretty beige.

Hey CA$H,
Can we see some photos of your mac with the plastic off? Or would this reveal your enitre secret project?
Feel free to blur any parts of the photo you don't want us to see.
Thanks,
infiniti

Ca$h, are you taking out the metal shielding over the CRT? If so, please send pictures of it because I would like to do the same. I always thought it kept in too much heat, and if it isn't structural or anything. . .

Um... you really don't want to take that metal shielding off... I think its a faraday cage...
Stops EMI getting in, and out...

yeah, I can take pictures of it naked. Maybe. See, I dont have a digital camera, and right now my Canon Autoboy whatever has dead batteries. They're this really obnoxious battery size, like gimpy AA's, so they're like 5 bucks each, and I'm poor right now... argh. Wish I had a freaking digital camera.
And.. about the RF shield. I dunno WTF it is for. My radio still works, and the computer still works. It still has a shield around the back part of the monitor, but the big metal part is gone.

Well, if you do happen to get a chance to take those pics, please post them as I'd be interested to see which shield part you have taken off...
Maybe the back one is the faraday cage and the large one just structural - thats if it is a faraday cage!

The RF shielding is for the protection of your human being. If you keep working on your naked iMac this ways you are going to have a bad prostate, a brain tumor, you will grow a third leg on your skull, your ears will drop and your kids will be nasty caterpillar (what movie is this? It should be pretty easy).
...No, it is not cool. You won't get superpowers.

I dont think so. The newer iMacs dont have this shielding either. It has to be safe if all the new ones look like that, right?
Anyway... there is still some shielding on the back end of the monitor, just not around everything.

Godfather, thanks for confirming what I thought
Not about the 3rd leg and all though... 
Ca$h, the newer iMacs have better technology, including shielding in the iMac shell, and also the shortneck CRT's I imagine aren't quite as 'dangerous' as the older ones...
They prob have a much safer RF output level...
Trust me, put that cage back on.
After you get some pics, that is

Please explain how colored translucent plastic is "shielding". You can see the CRT tube right in the new iMacs, and there isnt shielding ont hat thing. I really think that what I did is probably safe, because I still have an emi shield around the back of the monitor.

PS: Does the glass somehow stop this radiation? Dont think so. THats my theory why people get brain tumors. Heh.

I seem to remember reading one of the marvels of the design of the DV's was how the shell acted as the shielding... I'll look for the article or some info on it.

Ca$h,
The new CRT's use a different shielding. They have a conductive carbon shield right on the CRT itself.
So it is best to keep the shielding on in your case. I mean, even with the shielding off the view inside the iMac will hardly improve since you would just look at the copper side of the PCB's

So whats going to happen if I keep it off? Is it an EMI shield, or a RF shield? If its an RF shield it'll just screw up my radio, right? And if its EMI, what could happen?

RF won't only screw up your radio...
I'm not sure whether its just RF, or a whole range of EMI or what, but it has been known to do some damage...
Anyone care to elaborate?

Let it go. I think Mr. Cash needs that 3rd leg, for ... something.
I have to add that I remember something about the new cases being some kind of shield...

Not the case but a carbon layer on the CRT itself is the shield.
It is not just RF but EMI.
A picture tube also radiates X-Ray's normally. Not good if you get exposed to that to long. Test it by pasting x-ray film on your ack and put the imac minus shield aginst your belly. (just kidding)

correction to my last post.
Only the iMacII CRT's have the carbon shield.
Older imac's NEED the metal shield to keep you healthy.

dammit. Now I gotta take it apart again. oh well. Hrm. I should start selling a "field strippable" imac kit. It would include all the screws necessary to dissassemble the thing without hand tools. Like knobs and stuff for some, or maybe the ones that you sorta HAVE to use handtools good be some super tough grade 8 type hardware so it doesnt strip.

Also, in the newer iMacs they moved all the radiation generating components to the bottomside of the logic board (in the solid color part of the iMac) and shielded it there.
So along with the shielding painted right on the CRT tube (which some people thought was painted on the plastic surrounding it at first), no more unsightly metal structures.
Do you think that Apple wanted those ugly things there? Be safe, and leave them be...
