Well it's a trial and error thing, and I am willing to donate one ipod for experiment. But not sure if there will be any harm to my amp and/or iem's.

If you've swapped the internal hdd for the cf card, there'll be enough space in the 30gb back for the film caps.
Depends on the exact size/brand of the film caps, etc. They are all different sizes. A 2.2uf...sure, that's pretty safe to say it may fit. But you start getting up to 4.7uf you're looking at pretty tight squeeze. So, just saying a "film cap" will fit is a bit vague. Electrolytic caps though will pretty much fit inside no matter what. But don't sound as good, imo
And guys, don't go all willy-nilly picking out values. 3f? Whoa is right. There is a formula to choose the proper value that won't mess up your frequency response. For the voltage rating- the cap will only block DC up to its rating, and that's the whole reason we're using caps, right? To block DC. I would be weary of 2.3v myself.
That said, I am curious to hear how a "super" cap may sound. Looks a bit just like an electrolytic?
Here's a handy calculator to help solve for the proper capacitor value:
I realized the supercaps are electrolytic caps and have the weird numbers for the capacitance and voltage. Since it's super, why not give it a try? Let's just hope this won't turn out to be a supercrap. :)
On the film size, if you use the 4.7uf's as I have been using then don't even try to fit them in the thin model.
Personally, I'm holding out for "uber" caps and then trying to replace the iPod hard drive with a small piece of brain tissue that can work with your levitation tech. This should be able to bypass caps and wires and cables and headphones altogether and telepathically transmit the music from the iPod to your cerebral cortex. Talk about a pure signal!
I've got a few more things to work out though. Like a brain tissue donor and telepathy. I'm probably going to need a lab coat and crazy hair as well. So sit tight.
For anyone who cares, here is a dock connector I did recently. The user wanted to retain the stock hard drive and use film caps. So I hollowed out the dock and were able to fit them inside. Lucky they were 2.2 uf as they were pairing with an amp that had (edit:) 50k input impedance. So 2.2 was all it needed. Slightly bigger may even fit in there (3.3?) but that's just a guess.

Send me a chunk of your brain in a cooler. I'll get started. Throw some poke in there while your'e at it! A guy's gotta eat. That's what I miss most about Hawaii. Poke. Mmmmm
Oh, and Dminor is right, 4.7 film caps won't fir in a thin back. Aaaaaalmost, but not quite.

Nice job my friend. But you forgot to throw in some Kermits there. LOL.
How about this nasty Hamachi? Don't let the looks fool you. :)
I'm actually going to get rid of the giant caps in the one iPod (you can see it in the back of that one picture) going to try the kemet (kemit? Kermit?) in that one so I can compare identical iPods but one w/ Wima and one w/ kemet.
Whatever is better will go in both iPods then probably sell one off.
As far as the Hamachi, that'll work. Although it does give me flashbacks of a porta-potty at a Grateful Dead show.
