I've looked around a bit, but can't find anybody saying whether there is room in the new slim iMac for an extra internal SSD. I used this tutorial about a year ago to add an additional SSD to my Mid 2010 iMac and would like to do it with my new one. Since the iMac ships with Fusion Drive as an option, might there be a second bay and connector (or at least space for them) inside the chassis?
Is there any documentation showing whether the 2012 iMacs have room for multiple drives?

It can be done, but I’m not sure which SKUs it applies to, or that it’s particularly advisable.
Both the 2.9 GHz and the 3.1 GHz 21.5″ iMacs have space for a second drive bay, and there’s an iFixit tutorial explaining how to install a second drive. (iFixit usually tear down new hardware within a day or so of release, and have a lot of tutorials for things like hardware upgrades and repairs).
Currently their page for the 27″ model doesn’t have such a tutorial. However, there’s a page on their forums where people are discussing associated teardowns and the possibility of such an upgrade. The poster ifixit611 writes:
They conclude that they won’t be performing the upgrade before iFixit or OWC provide a proper “kit”.
So it sounds like, in theory, you could perform this upgrade on a 27″ iMac, and the instructions from iFixit for upgrading the 21″ would probably be helpful in this regard. That said, hardware is not my area of expertise and I generally get twitchy about opening up iMacs. Do at your own risk, etc.
